    The Hydra has tentacles that have barbs in them that whenever something touches it, the hydra shoots back, paralyzes its prey and eats it. They are also fresh water organisms. The Hydra belongs to the phylum Cnidaria, also called Cnidarians because they can sting their prey. Fungi are organisms that used to be in the water then migrated to the land. Now they live on trees. They are sometimes used to help clean up chemicals that have spilled. The fungi eat the chemical and make the contaminated area completely clean.

    The Hydra is a fresh water organism. Their phylum is Cnidaria, but they are also know as Cnidarians. Their tentacles sting prey and drag them to the mouth of the hydra. Their main source of food is Daphnia. They reproduce in three ways: budding, regeneration, and sexual reproduction.

    I learned the hydra are freshwater organisms and are also called Cnidarians. Hydra eat food by stinging it with its tentacles. They prey then becomes paralyzed and is brought into the hydra's mouth. I also learned that a healthy hydra reproduces a bud every 4-5 days. Fungi are one of the 6 Kingdoms of Life. Most fungi are poisonous to eat but they are very good decomposers.

    The hydra is a very interesting organism. It can move f it wants to but most of the time it spends its day stuck to a rock or other surface in water. Like fungi grow or stick to the spot where their food is. Hydra stay in one spot and feed on anything that floats by them. They catch their prey with their tentacles. Hydra feed on organisms like the daphnia where fungi eat dead organisms or food like bread. Some fungi even are used for medicinal purposes. Both he hydra and fungi were fun an interesting topics to learn about.

    The hydra is a living organism that paralizes its prey then eats it. The fungi was very interesting to learn about fungi grow or stick to the spot where their food is while the hydra stay in one spot and wait for something to float by.

  6. The Hydra is amazing! Its so cool how its tentacles grab its prey firmly, so its a pretty rare chance of the prey escaping. Hydra are multicellular organisms and they live in fresh water. The Hydra's bodies are thin, hollow cylinders with 5 tentacles. Hydra reproduce many ways, one way is budding, budding is when the hydra grows another hydra off its bodies.
    Fungi is a member of a large group of eukaryotic organisms. but fungi isn't consider a plant nor an animal but kind of a mixture. Fungi eat but they hunt for food or make it they actually live on it. In a way they are like hydra they grow another organism just like that. Some fungi can be poisonous so be careful when you play around mushrooms. Over all looking and learning about the hydra was an remarkable experience and the fungi we still learning about.

    We learned a lot about hydras this week, as well as fungi. The Hydra belongs to the phylum Cnidara, also called Cnidarians because they can sting. Hydras are known for their tentacles that are used to sting and catch prey. Once the Hydra has a grasp of the organism, they bring it into their mouth. The Fungi kingdom is one of the 6 kingdoms of life. They are normally made up of many tiny tubes called hyphae. Even though most are poisonous, they are great decomposers, and most fungi are used for medicinal purposes.

  8. I learned that the hydra is a freshwater organism that preys on organisms such as the daphnia. It eats its prey by paralyzing it with its stingers and sucks it up its body, into its mouth. It stays attached to something like a rock its whole life waiting for its prey. Their reproduction method (budding) is an advantage to their population because some can reproduce in up to four days! Therefore they don't just decide to start budding, it is rather a natural part of its life. However, fungus lives on its prey rather than hunting for it. We may only think of these fellows as pizza toppings but they actually help clean up toxic waste or chemicals. Furthermore, they also save lives when they are included in some medicines we might know. This is what I learned on the hydra and fungus.

    I learned that hydra have tentacles. The cells in the tentacles can pull food towards the hydra, sting it, and stuff the food down inside the tube to be digested. Also, some kinds of hydra, for instance, have evolved a relationship with one-celled prokaryotes that can photosynthesize food for them. The hydras let these algae live inside them and the algae eat what the hydra doesn't want and spits out what the hydra does want. I learned that fungi reproduce by letting spores out into the ground that grow into new fungi.

  10. The hydra is an amazing animal that hase 4-8 tenticals on it's mouth and can live only in fresh bodies of water. The hydra can also reproduce by budding, to make an organism out of another, witch means it doesnt need a mate to reproduce. The hydra moves my summersulting around in the water and does'nt move otherwise. The hydra is an extraordinary organism, and can facinate the mind.

    Today I learned that hydras move by doing flips. They can also obtain food by paralyzing their "food.' I also learned that they can expand their digestive cavity.

    Well learned a lot about Hydras and Fungus. Hydras are a part of a group of animals called Cnidarians. Cnidarians also include jellyfish. Hydras consume its prey by capturing it in its tentacles that have a stinging features. Hydras also have multiple ways of reproduction. Fungi kingdom has about 1.5 million species. The umbrella-shaped structure on top is the reproduction feature in a mushroom. It produces spores that float away. The spores will then land and germinate on a suitable spot.

  14. I learned much about the hydra and fungus. I learned that hydra feed by stinging their pray with its tentacles. The fungus feeds by decomposing on other organisms. The hydra reproduce asexually and by regeneration. Fungi reproduce asexually by spores. Hydra can move by summersaulting in the water and fungi don't move at all. This is what I learned.

    I learned that hydra have tentacles that sting other prey. Once they have the organism they bring into its mouth. Their phylum is Cnidaria and they're freshwater organisms. Also, Hydra can reproduce three different ways. I learned that Fungi are one of the Six Kingdoms of Life. They are both single and multi-celled. Fungus are eukaryotic and reproduce by releasing spores. Most of them are poisonous and are even used for medical purposes. Both of these topics were great to learn about!

  17. I learned that the hydra, or Cnidarians, are small organisms that flip to move in freshwater. These organisms sting other organisms and bring them near their mouth so they can eat them. Hydra can reproduce sexually or by budding. Budding is a process in which the hydra grow a small bump and eventually it will become another hydra.
    While hyrdra have to find their food, fungus grow on their's and feed off of it. Many fungus are good, but some can be very bad. While you may think mushrooms are harmless, think again, because many of them are poisonous. Not all fungus are bad though, many are used to make medicines. I learned a lot about the hydra and fungus and I hope we can learn more about them.

  18. Hydra paralyze their pray with their tentacles and then slowly consume it. It’s a multicellular organism that can reproduce by budding, regeneration, and sexual reproduction. Fungi are great decomposers. They are one of the six kingdoms of life. They reproduce by letting spores fly away and whenever they land on a place suitable for growing, they survive.

  19. the hydra can reproduce sexually and asexually. they reproduce asexually by budding. I think this is cool because it is an exact copy of you. they feed by using their tentacles to paralyze their prey. they then suck them into their digestive cavity and break down the organism. then it spit the remains out of its mouth.

    It was very interesting learning about fungi and the hydra. Hydra sting their prey with their tentacles, once the organism is paralyzed from the sting the hydra eats it. Fungi obtain food by feeding on dead organisms or getting it from whatever their spores land on such as what breadmold does. Hydra and fungi are very different but both are very interesting to study.

    This week we learned about Hydra and Fungi. Whenever the Hydra feels an organism brush against one of its tentacles, it instantly traps it, paralyzes its prey and then eating it. These freshwater organisms belong to the kingdom phylum Cnidaria. I don't think that these fancy reproducers will ever be considered endangered due to the fact that they have three ways to reproduce. Three! One of the three is budding, when the adult hydra actually grows out another one of its kind! Weird much? I think so! Fungi are pretty cool/ weird organisms too. They used to swim along with the other creatures of the see but then, they slowly started to become neighbors to all the land animals. Plus they are sometimes used as mops. This is only because they help clean up most chemicals. Also, has your mom ever told you "Don't play with your food?'' Well, these organisms live on it! No need for hunting! This week we learned some freaky facts. However, I must admit itwas fun learning about Fungi and Hydra.

  22. The Hydra interested me the most.They're little creatures that live on the ocean floor. Usually, Hydra eat daphnia but I noticed they eat other things like minnows. Hydra shoot out poison barbs when prey pass through their tentacles. Therefore the Hydra takes in its prey to its mouth. It's amazing how they reproduce through different ways like budding. But if a broken part of a Hydra has fallen it can grow a new Hydra. But most Hydras reproduce sexually. Fungi usually grow off of things like bread and live off it. Therefore Hydras are different from fungi. Fungi live off of objects. But Hydra can move around doing somersaults and catching prey.

    I learned that hydra lives in the ocean and preys on microscopic organisms like the Daphnia. It eats by paralyzing the prey with its tentacles and then sucks it up in its body. I also learned that it reproduces by asexual form called budding. Their is and advantage if the hydra species is dying and if there is not enough male/female hydra in the environment. Fungi doesn't hunt its prey however but instead drains energy from them. Plus you don't use hydra as a pizza topping and Mario doesn't eat hydra.

    I learned that the Hydra is a very interesting creature. It paralyzes prey with stinging cells in tentacles, and slowly feeds on it with released enzymes. It has three known was of reproduction: budding, regeneration, and sexual. The advantages of having three ways to reproduce is that they can grow back if there's only one remaining.

    Fungi, on the other hand, are very different, as they can be multicellular, or unicellular. They reproduce with spores(similar to seeds, but are produced by a fungus, not a plant). Fungi don't hunt for and chew they're food, but they grow on it. They are born onto a plant or animal and absorb the nutrients they need from it. Black bread mold is an example of a fungus, which is born onto bread and feeds off of it. It reproduces by spreading spores throughout the bread slice or loaf. It doesn't obtain it's color until a special part grows, so you could be eating bread with mold on it and not notice!

    Hydra are very fantastic and very interesting organisms to study! They have tentacles that help paralyze its prey and feed itself. They vary in color and can reproduce sexually and asexually by a process called budding. The part I found most interesting about the Hydra was the way it can eat and catch a Daphnia. It spreads out its tentacles very swift-like and pulls the organism to its mouth. Kind of reminds me of Squidward and his tentacles.

    What I learned about the hydra is it uses it's tentacles to paralyze and bring in it's prey. It has three ways of reproduction: budding, regeneration, and sexually. When a hydra buds, another smaller hydra sprouts on its side. It can do this every 5 days. If an creature attacks it, the hydra can regenerate a whole body, and head. When the weather gets colder, the hydra will reproduce sexually to make a cluster of eggs. These eggs can survive the cold tempuratures of the water while the parents can't. I also learned about fungi.The fungi is a kindom of their own. Fungi cannot produce clorophll and have to find a host to feed on (dead wood, rotting animals, ect.). To gain energy from its host, it produces mycelium which is the body of the fungus. The top cap part is where it reproduces. Take bread mold for an example. The place where it eats is where you see blue on the bread which is the mycelium. The black dots you see in the fluff is where the fungi reproduces. It goes around when the black dots open and all the spores come out.

  27. They hydra is a small organism in the kingdom protitsa. The hydra is similar to a jellyfish because they have stinging cells. These Cells are used to paralyze the hydras prey. These organisms can expand there mouth and this helps to eat larger organisms. Although the hydra does not look alive it reproduces and digests so it is alive. They have a degestive cavity. Methods hydras use to reproduce is budding and/or sexually reproducing. I learned alot about hydras in this week. We also looked at a perserved budding hydra in the microscope. You could see it with the bare eye but seeing it in the microscope gives alot more detail.some parts the hydra has are the tentacles, moulth, and digestive capivity

    The hydra is not permantly stuck to an object like a mushroom. A hydra is actually an animal. it can move when it wants.
    I learned that when an animal stings, tiny things are injected into you. It's not an alergic reaction.

    I learned that Hydra are very interesting creatures. They trap and paralyze their prey in their tentacles. The Hydra then slowly takes the prey and digests it.

    I also learned about Jellyfish this week. Jellyfish were around before the dinosaurs. To eat jellyfish sting their prey with their tentacles which release a venom that paralyzes their targets. Jellyfish don't target humans but because they drift in the water, someone close to it could get stung. Even after the jellyfish is dead it can still sting someone for a short amount of time after death.

    I learned that the hydra is one of the simplest multicellular organisms. They are a member of the phylum Cnidaria. The hydra can reproduce sexually and asexually. They can also sting their prey and use their tentacles to pull it towards their mouth to eat it.
    Fungi break down plant and animal remains and wastes and release their nutrients back to Earth. They are also symbiotic, which means that they exist in a long-term relationship with another organism. Some fungi are deadly if you eat them, but many are helpful too.

  31. This week, we learned so much about Hydra and Fungi. Hydra belong to the phylum Cnidaria and they are called Cnidarians because they can sting their prey. Hydra are freshwater organisms. They have a tube like body and tentacles that it uses to paralyze its prey. They reproduce asexually in the form of budding, where a new organism is produced from the body of another. Also, Fungi are their own kingdom. The cap of the fungus is where the reproduction happens, and the stem underground is where their energy is obtained. Learning about both Hydra and Fungi this week was very interesting.

  32. This week we learnt a lot about the hydra and fungi. The only diffrence in the way the hydra and fungi are stuck o the ground is that fungi grows from the host unlike the hydra which when given birth picks a spot and lives in it stuck. Other things i learned about the hydra is that there tentacles can stick a prey and suck it into its mouth. Also, that since it only has one hole, it eats through it and gets rid of waste through it. Yes, i also had a disgusted face when i heard that. In addition, i learned that fungus is all in the air but it just sticks to its host and builds roots.Overall, this week i have learned a lot of cool facts about these animals

    this week we learned a great lot about Hydra and Fungus.we learnt that the Hydra can reproduce sexually and asexually, through budding or mating. we also learned that Hydra reproduce sexually in the medusa stage and asexually in the polyp stage. the hydra are cnidariens, which means that they have stinging cells that can paralyze or poison its prey. its tentacles can draw the food into their mouth. because the hydra only has one opening, it gets rid of waste through the same hole
    the fungi are immobile all the time, so they have to live on their food to swallow it. they reproduce asexually using spores. some fungi include mushrooms, yeast, and the puffball. we sure learned a lot about the hydra and fungi this week.

    This week, the hydra and fungi were our topics. These two organisms are very interesting. For example, we watched a video of a hydra eating a daphnia. It first stung it with its tentacles, paralyzing the daphnia. After that, it sucks it into its mouth, using a vacuum type of suction. This type of defense mechanism makes it very easy to attack organisms of all sizes. The hydra also can reproduce by budding. This is when a small lump starts growing on the side of a hydra, and soon grows full sized. That type of reproduction makes them almost invincible. They can never go extinct because of this, because all they need is a single hydra. In addition, the hydra is actually an animal, believe it or not. Fungi, on the other hand, are a kingdom of their own. They are decomposers that feed on dead organisms, in which they break down. They can grow almost everywhere that they can feed on, such as bread. Bread mold is very common, and we are even looking more into it tomorrow!

  36. The Hydra is like the fungi because it can stick to something,only if it wants to. Un like the fungus, the hydra has an option to float around or to stick to something.The Hydra is also called a Cnidarian. It obtains food by stunning its prey and pulls it into its mouth with its tentacles. It reproduces in three ways. Budding, regeneration, and sexual reproduction. Also, the hydra is a freshwater organism.Overall, I loved studying the Hydra!

They would use the tenticals to paralyze their prey and then they would pull the organism into its mouth. We also learned that fungi are not plants. They are there own kingdom. They don't have seeds, they have spores for reproduction. Fungi also live right on top of their food source, so, they don't really need to go far to find food because they are living on top of it.

    The Hydra moves under water by doing little cartwheels and it paralyzes its prey by using its tentacles then tangling it up and moving it up to its mouth. The fungus must be rooted to something that it can take energy from to survive.

    This week, my class learned about the Hydra. The Hydra is in the fungi kingdom. The Hydra is similar to a jelly fish because of it's stinging tentacles. One peer in my class called it a squid. The Hydra reproduces asexually, and sexually. It reproduces asexually when it produces another budding hydra off it's side. The baby budding hydra eventually falls off, and becomes its own hydra. It can reproduce sexually when a male and female hydra fertilize the egg. Under a compound-light microscope, the hydra we studied was red, and I personally found it looked similar to a jellyfish. I have really enjoyed learning about different kinds of fungi, and tommorrow, we will be studying bread mold! Mrs. Zazzali told us that she is buying a fresh baked loaf of bread and a store-bought loaf to see which will get moldy quicker. Personally, I felt as though the warm fresh baked bread would grow faster, seeing as fungi like warm dark bread boxes, but I guess we will wait and see!

    The hydra is a fascinating creature. It traps it prey by catching it in the tentacles and injecting it with poison stored in the stingers.It then eats it food and digests it in the digestive cavity. It moves by doing somersaults, which I can't do.
    We also learned about fungi. They have their own separate kingdom. The use spores to reproduce not seeds. They live on their food source and produces mycelium. Did you know that Fungi have more in common with animals than plants?

  42. I learned that the Hydra is able to have the ability to sting other organisms with its tentacles. It is similar to the Jellyfish and they both belong to the group called cnidariens which is a group of organisms that can sting. Fungi live on their food since their immobile. That is where it gets most of its nutrients. Some types of fungi are mushrooms and bread mold. Some are healthy and some are poisonous. Theses are both interesting organisms.

    These past few days I learned a lot about the Hydra and fungi. I learned that Hydra are organism that can reproduce in three ways and that they have sting cells and are related to the jellyfish. For the fungi, I learned that they usually grow on their food source, forming hyphae into mycelium. Both of these organisms were interesting and I hope I can learn more about them.

  45. Hydra belongs to a group of organisms called Cnidarians. Hydra can reproduce many ways, an example is budding. Budding is when a small bud breaks off into a hydra, the bud then grows into a new Hydra. Hydra gain food by first paralyzing an organism. Then the hydra pulls the organism closer with its tentacles to eat it.

    Fungi are one of the six kingdoms of life. Fungi can be poisonous, however some are found in food. Fungi reproduce by spores, which are found at the part sticking up from out of the ground. Some fungi get food by attaching to it and eating it. An example of this is bread mold.

    We learned that if the Hydra stings its prey, the prey gets paralyzed. Then they put the prey into their mouth and when they digest it it comes back out of their mouths. We learned that the Fungi is a separate kingdom and they feed on dead organisms. We are learning more about the Fungi tomorrow.

    Hydra are not stuck to organisms like Fungi. I learned that Hydra paralyze their prey, and then use their tentacles to pull them into their mouth. They eat organisms such as Daphnia or Black worms. However, Fungi grow on organisms, and rely on the organism they grow on.This is because fungi are not capable of obtaining energy on their own.

Also, the Hydra paralyzes their prey and pulls them into their mouth to eat them. Unlike the Hydra, Fungi grow and rely on organisms to live. They have to do that because they cannot create food or obtain energy on their own.

    Recently in Science class, we have learned learned much about the hydra and fungi. The hydra can use specialized cells containing stinging structures called nematocysts. They can shoot out threads that can paralyze an organism. Then, the tentacles would force it into its digestive cavity. Also, hydras can reproduce in various ways. They can reproduce by budding, regeneration, and when it gets cooler they can reproduce sexually. Finally, Hydra has no circulatory systems, heart, blood vessels, or skin.
    We have also read about the fungi. They can’t capture their own food, they can’t make food from sunlight, and most of them can’t even move around. There are almost 1.5 million different species of fungi. They are unicellular and multicellular. Fungi are typically made up of tiny tubes called hyphae. Examples of fungi are mushrooms, yeasts, lichen, etc. They usually get their food by attaching themselves to nutrients and absorbing it.

    This week I learned how the hydra, a freshwater cnidarian (meaning it has small stingers that shoot out when its nervous system feels something), can reproduce by budding. I found this particularly interesting because before that, I only new about sexual reproduction and regeneration. Budding is when a small growth appears on a hydra then sprouts tentacles, detaches, and forms into a new hydra.

    The Hydra can produce asexually and sexually. Which is helpful because if there is no other Hydra to mate with, it can produce asexually, budding, without a mate. I thought this was interesting because I have never heard of anything like it.

    The Hydra was very interesting to learn about. They can reproduce sexually and asexually. If Hydra don't have a partner, it can always reproduce asexually by budding. Budding is what happens when a bud forms from its body and is then another Hydra. This was a very interesting organism to learn and look at. Atleast for me it was cool.
