description of fungi
- eukaryotic
- multicellular or unicellular
- heterotrophic
- contain no chlorophyll
- cell walls of chitin
are most fungi cells haploid or diploid?
haploid
fungi types:
- zygomycota: bread molds/ sugar fungi
- ascomycota: sac fungi
- basidomycota: club fungi
ascocarps produce how many ascospores?
8
in lichen, what is one benefit that the fungus receives and what is one benefit the algae receive?
the fungus provides the structure/protection for the algae and the algae provides the food supply for the fungus
