Bacteria Help?

True or False?





1. Fungus cells are eukaryotic





2. Fungus cells can make there own food





3. Fungi spread from place to place through the production of mycorrhizae





4. Tenicillin is an important anti-biotic produce by fungi





5. Lichens grow on the roots of plants to help them grow.











Plz help

Bacteria Help?
This has nothing to do w/ bacteria, fyi...





1. true


2. false (and it's "their" own food, not "there")


3. FALSE (the previous person was wrong); fungi spread by hyphae. Mycorrhizae is the association between a plant and fungus.


4. penicillin? tenicillin is not a word


5. false--algae + fungus, not plant + fungus
Reply:True





False





True





Not sure if you misspelled this, but I'd say FALSE. It's penicillim.





False
Reply:Why do you say that you need bacteria help? You are asking about Fungi which is a very different Kingdom.





1. True


2. False - Fungi are heterotrophs


3. False - Fungi spread by hyphae/spores


4. False - Penicillin is an antibiotic


5. False - Mycorrhizae grow on plant roots and help them grow
Reply:1. True


2. False


3. False


4. Penicillin? TRUE!! It comes from penicillium which is a FUNGUS!


5. False
Reply:These are not the expected answers to your home work but will help answer your home work quesitons. Hope it helps!








1. The eukaryotes include ourselves, other animals, plants and fungi and a rich variety of micro-organisms (protists). CAn you answer the question now?





2. Fungi absorb nutrients from living or dead organic matter (plant or animal stuff) that they grow on. They absorb simple, easily dissolved nutrients, such as sugars, through their cell walls. They give off special digestive enzymes to break down complex nutrients into simpler forms that they can absorb.Most fungi can best be described as grazers, but a few are active hunters. Hunter fungi prey on tiny protozoa and worm-like creatures called nematodes. Some produce a sticky substance on their hyphae, which then act like flypaper, trapping passing prey. A species called Arthrobotrys dactyloides sets snares made out of loops formed by its hyphae.


3. The word "mycorrhizae" literally means "fungus-roots" and defines the close mutually beneficial relationship between specialized soil fungi (mycorrhizal fungi) and plant roots.


4. Try Penicillin and that is an antibiotoic produced from fungi!


5. Lichens grow in the leftover spots of the natural world that are too harsh or limited for most other organisms. They are pioneers on bare rock, desert sand, cleared soil , dead wood, animal bones, rusty metal, and living bark. Able to shut down metabolically during periods of unfavorable conditions, they can survive extremes of heat, cold, and drought.
Reply:True ( eukaryote means cells have a nucleus)


false ( only plants that photosynthesise and chemotrophs at the bottom of the ocean are preoducers....fungi "eat" other things)


Hmmm fungi generally spread by SPORES or thru the MYCELIUM/HYPHAE....so False


False..assume they mean penicillin


5. FALSE....mycorrhizae do....myco = fungi and rhizea = roots
