What kinds of environments do protozoans like?
Areas with lots of water

Can chromists be single-celled, multicellular, and/or colonial?
All of the above
300
What are spores?
Reproductive cells that are protected by thick cell walls
300
What is budding in yeast?
A process that involves part of the cell pinching off to produce a new yeast cell
400
What about chromists makes them similar to plants?
Chromists are autotrophic

What's the difference between perfect fungi and imperfect fungi?
Perfect fungi - can produce both sexually and asexually
Imperfect fungi - have not been observed to reproduce sexually

On the mushroom diagram, label:
hyphae, mycelia, fruiting body, stipe, cap, and gills
400
When would a fungi do sexual reproduction?
When asexual reproduction is unfavorable

List four characteristics of protozoans.
Usually motile as adults
Found in areas with lots of water
Usually heterotrophs
Most live in other organisms

Explain the five steps of reproduction in black bread mold.
Two hyphae from different mating types grow until they touch each other
The hyphae fuse where they touch to form a zygosporangium (a diploid zygote) through sexual reproduction
The zygosporangia forms spores via meiosis
The spores germinate to form hyphae through sexual reproduction
As the hyphae grow, asexually formed spores called sporangiospores form and are released

What are three unique characteristics of fungi?
Heterotrophic
Lack chlorophyll
Have chitin

What is the difference between sac fungi, club fungi, and cordyceps?
Sac fungi - cup shaped
Club fungi - the only fungi that can be classified as "mushrooms"
Cordyceps - parasitic fungi that turns insects into zombies
