to alter growth form from yeast to mold in response to change in environment?

dimorphic

spores produced by a fungal cell through multiple cell cleavage within a saclike head?

sporangiospores

a saclike head where spores form and are held?

sporangium

tubular threads that make up filamentous fungi?

hyphae

an organism that normal doesn't cause a disease but can become pathogenic under certain conditions?

opportunistic

name two types of hyphae?

1. septate 2. aseptate

colony morphology?

1. used to make beer and bread 2. reproduce by asexual budding 3. white/gooey like cream cheese

name of yeast?

Saccharomyces cerevisiae

name a pathogenic yeast?

candida albicons

name a yeast that causes endogenously (already existing on body) acquired infections?

candida albicons

free spores not enclosed by a spore-bearing sac, but produced in a chain-like manner?

conidiospores

a disease causing organism?

pathogenic

name an opportunistic fungus?

Aspergillis niger

sabouraud's dextrose agar plate is exposed to air, within a week mold is seen growing on the plate. how did the mold get there?

1. doesn't grow bacteria, so mold can grow 2. spores in the air

how do fungi differ from bacteria?

1. fungi- eukaryotic, multicellular 2. bacteria- prokaryotic, unicellular

why don't most bacteria grow on Sabouraud's dextrose agar?

1. increased pH 2. increased sugar
