Lecture 6: Kingdom Fungi Flashcards
What is in the structure of a fungus?
Chitin, mycelium, and hyphae( septa and coenocytic)
What is chitin?
The fungal cell wall
What is mycelium?
The interwoven multicellular fungal mass
What is hyphae?
The fungal filament
What is septa?
They are divisions for the cells in the hyphae and have pores for sharing resources
What are coenocytic hyphae?
Hyphae that have no septa and are continuous multinuclear cytoplasm.
What is a feature of fungi?
They have unknown flagellated protists ancestor.
What are some phylum in the fungi kingdom?
- Chytridiomycota
- Zygomycota
- Ascomycota
- Basidiomycota
What are some characteristics of chytridiomycota(chytrids)?
They translate to “little pot fungus”. They are the earliest lineage of fungi. Some may be unicellular but other have mycelia.
What is a zoospore?
A flagellated spore
What is chytridiomycosis?
A fungal disease in amphibians that is linked to worldwide decline and extinctions.
What are some characteristics of zygomycota(zygote fungus)?
It translates to “joined fungus” and has coenocytic hyphae
What is a genus of zygomycota?
Rhizopus(only) stolonifer which black bread mold
How does zygomycota reproduce?(Asexual)
Asexual reproduction where the mycelium forms sporangia that produces genetically identical zygospores.
What is kariogamy?
The fusion of the nuclei
