Large or small group?
A one ppoint, __ was considered this type of fungi.
__ are a majority; _ are minor.
What is different about this group?
their hyphae are coenocytic; no sight no crosswalls
Why are they not water molds?
How are they similar to chitin?
because they have chitin.
how they form spores
Explain asexual reproduction.
produce sporangia (develop similarly to water molds)
- between each part, there are nuclei
- each nucleus gets a cell wall to become a spore
- two mating strains
- if growing in the same vicinity, peglike structures form that come off the hyphae that enlarge (progametangium)
come together and fuse--> zygospore
In this, the nuclei fuse--> coenozygote (when the mating strains come together just before forming a zygospore
must have both mating strains--> gametangia--> young zygospores (coenozygote)--> zygospore--> sporangium--> spore
What is pilobilus
a zygospore that always shoots spores towards the light
What disease do they form?
black bread mold
