Why were fungi and plants once classified together?

-Many fungi have leaf-like growths.
-Fungi have root-like structures.
-Fungi and plants were not classified together.
How do some fungi move?

-building up chitin
-There are no fungi that are motile.
What is a spore’s function?

-migration
The existence of lichens in a forest means that _____.
-bacteria may be present
other organisms may have had trouble growing there
-autotrophic algae may be present
-All answers are correct.
Why does a fungus produce so many spores?









to increase the nonmotile spores’ chances of reproducing



so that motile spores can travel by air to populate new environments





to stimulate germination



to be able to compete with other species of fungi


Which of the following increases the amount of nutrients that a plant can absorb?









mycorrhizae



pathogens





lichens



decomposers
Algae and bacteria receive _____ when they are part of lichen.
water



nutrients





protection

zygomycete





ascomycete



imperfect

What is the main ecological role of fungi?
*producers *consumers *decomposers *parasites

The formation of a gametangium requires _____.









hyphae from two different mycelia



two different hyphae from the same mycelia





the formation of long filaments



the growth of fruiting bodies

Why does the budding process NOT produce spores?





Spores are unnecessary to asexual reproduction.



Budding produces fruiting bodies.





The new cell is a complete organism.



Budding does produce spores

Which of the following are characteristics of most fungi?

A scientist is collecting fungi samples. How will she be able to identify an ascomycete?
*She will look for spores contained in sacs.
*She will look for spores contained in fruiting bodies formed in a ring above ground.
*She will look for spores that are inactive because conditions are not right.
*No answer is correct.

Don't you have a textbook or google? These do not strike me as questions that you can not answer because you do not understand the principles. Look, it isn't too hard:
1) http://en.wikipedia.org/wiki/Fungus, first sentence
Fungi are not green, hence they do not contain chlorophyll, making them likely to be... ___
And so on
