what are fungi most often associated with?

mushrooms

what are 3 different ways fungi exist as?

1. single cell

2. colony

3. multicellular organism (mushrooms)

what are the 2 different life cycles of fungi?

1. yeast

2. mold (hyphae)

the species of fungi that can alternate btw the 2 life cycle stages are called ____

dimorphic

dimorphic

the species of fungi that can alternate between the 2 life cycle stages (yeast & mold [hyphae])

Some fungi alternate btw the 2 life cycle stages. Why?

As a means of survival when environmental conditions apply pressure on the fungi

Other than alternating btw the 2 life cycle stages, how do some species of fungi survive harsh conditions?

by producing hearty spores that can become aerosolized and float around the environment to propagate more fungi after landing in a favorable place

many ocean-based algae have very distinct geometric shapes that are easily distinguishable under light microscopes

TRUE / FALSE

TRUE

diatoms are a type of ___, more readily known as ___

algae, plankton (specifically phytoplankton)
