Document Summary
Most fungi exist as either filamentous molds (cottony, fluffy colonies that grow up-think mouldy bread) or as unicellular yeasts (creamy, pasty colonies that grow out) Some fungi are dimorphic, which means they can switch between mould and yeast forms depending on temperature, co2 or another environmental trigger. Under some conditions, they can be molds, but under other conditions, they can be yeasts. Molds are good t spreading themselves all over the place with spores, but the yeast is a better form to maintain, since it is not as energetically costly. Composed of: mycelium-vegetative body made of many threads, looks like a cotton ball. The mycelium are a group of single tubes. If the tubes are lined up correctly, we create a mushroom. Anal hyphae-tubes that grow up from the agar. Vegetative hyphae: tubes that grow into the agar. If the tubes have internal dividers, they are septate hyphae. Conidia (asexual spores) are formed by specialized hyphae called conidiophores.
