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.
