Yeasts
|
unicellular fungi that resemble bacteria
|
|
|
hyphae
|
filaments of fungi
|
|
|
chitin
|
polysaccharide that makes up hyphae walls; also in anthropod exoskeletons.
Distinguish fungi from plants |
|
|
mycelium
|
mat of hyphae that forms body of fungus
|
|
|
septa
|
cross sections that divide hyphae of some species of fungi; coenocytes
|
|
|
dimorphism
|
ability to exist in two different forms
|
|
|
sporangiophores
|
specialized hyphae that look like upright stalks.
|
|
|
How do yeast reproduce?
|
form buds that pinch off to form new cells- called budding
|
|
|
What's a sporangium and its function?
|
it's a sac on top of sporangiophores, that make sporangiospores
ex: Rhizopus, which grows on bread, is a sporangiospore forming fungus |
|
|
How is a conidia different from a sporangiospore?
|
it's formed without the protection of a sac, on top of a conidiophore
ex: penicillum reproduces this way |
|
|
Describe the process of fragmentation
|
a septate hypha dries and shatters, releasing individual cells that act as spores
ex: fungus that causes athlete's foot |
|
|
How is the ability to reproduce sexually and asexually beneficial for fungi?
|
In times of hardship, they need genetic diversity to ensure that offspring will be able to better adapt themselves to the environment.
|
|
|
How do fungi sexually reproduce?
|
The equivalents of male and female- minus and plus- fuse their hyphae together to make diverse spores
|
