Hypha (plural: hyphae) |
Branching filaments that make up mycelium of a fungus |
|
|
What is the purpose of a vast network of hyphae? |
Large surface area-to-volume ratio (absorption) |
|
|
What is the purpose of mycelium and their hyphae? |
To secrete enzymes for extracellular digestion and to absorb digested nutrients |
|
|
Why are fungi called absorptive heterotrophs? |
They gain their energy from organic molecules they absorb made by other organisms |
|
|
Chitin |
The substance that makes up the cell walls of fungi |
|
|
Saprophytes |
Obtain food from dead organic matter |
|
|
Parasites |
Feed on living organisms |
|
|
Mutualistic |
When two species rely on each other and both benefit |
|
|
How do fungi reproduce? |
Sexually and asexually |
|
|
Phylum Zygomycota |
-Saprophytes -Common genus: Rhizopus -Reproduction both asexual (sporangia) and sexual (zygosporangia) - + and — mating types meet and form zygosporangia -Example: Phycomyces |
