hyphae

The main body of a fungus is made of little threads called hyphae. The overall body of a mushroom is called a mycelium. Occaionally the hyphae will grow and branch out, and the network will spread out in every direction. You can't see the hyphae because they are completely underground. The visible part (looks like a cap) is called the fruiting body. It's made of packed 's function is to produce spores. The fruiting body has two main parts; the lower part is the "stem", and the upper part is called the cap, which is where the spores are taken care of. The other types of fungi are called club fungi, sac fungi, and zygote fungi.



B. Obtain and Use Energy- Gisselle Molina
Fungi are consumers. All types of fungi have similar ways of obtaining food. Fungi obtains their food from living or dead things. It also obtains it food, by having hyphae which is like thread tubes, which is how fungi absorbs it's nutrient and obtain it's food. It goes like this: first, the fungi obtains it, then, digests it, and lastly, it breaks down for energy which involves many chemical reactions.


C. Reproduce-Harrison Sochor
Fungi are partially asexual, and they reproduce by producing spores, which look like little macaroni. Fungi that live in fresh water or wet soil produce spores with special tail-like things called flagella.
Spores can swim by moving their flagella. Spores are too small to see, and there are usually spores in the air around us. Spores appear (visually) when some kind of food or material is left out, and the spores in the air will all travel to it because it is a more favorable environment. When the spores grow enough inside their "shell", it will split open and the tiny spores will drift away.

D. Grow and Develop - Doug Arner
The fungi release their spores and they drift through the air. If they land on fertile land, they will grow into a hyphre but some species are very specific and can only live in certain areas. It will then continue that process until it becomes a full grown mushroom. Then it will release its own spores, and the process will start over. Out of the thousands of spores that are release, only a few will make it to full growth. Fungi can almost grow anywhwere unless there are no nutrients. The spores come through the fungi's gills but cannot be released unless gills are formed. Fungi can grow on anything including you! Some examples are athlete's foot, and other skin problems.Not all fungi have gills so they release spores by being passed by animals and bugs and such as the Stink Horn.

E. Respond to Stimuli Doug Arner
Some reactions to stimuli are fungus bending to light and moveing to water but not all fungus need light but they all need water.Also some fungi will react to chemicals by stopping growth and shutting down. some fungus such as slime molds will move towards nutrients, and if there is no water it will dry out and stop moving in a sort of plant like hibernation . Also slime molds might change shape according to habitat and apperance. Some fungi such as Earthstars will release spores if water touches them. ( watch end of video.)

(Spores need water so when water hits earthstar it ejects spores). There are tons of ways fungus respond to stuff everything they do is a reaction to somthing.

F. Exchange Gases with the Environment- Gisselle Molina
Fungi needs oxygen for respiration. That means that the only way they can get oxygen is by hyphae. Hyphae are some fungal filaments that look like roots. During the respiration the oxygen combines with the food and it breaks it down in to simpler substances then, the energy is released from the fungi. Most fungi gets it's oxygen from the air around it. The fungi that lives in the water gets it's oxygen from the water.
