4. The five fungal phyla can be distinguished by their reproductive features.

5. Division Chytridiomycota
mainly aquatic.
Some are saprobes, while others parasitize protists, plants, and animals.
chitinous cell wall
flagellated zoospores
the most primitive fungi

6. Division Zygomycota “Zygote fungi” (bread molds)
Zygote = “mated” hyphal strands
Live in soil, water
Some are parasites
