General Characteristics Flashcards
These are single vegetative cells that has a smooth, creamy, and bacteria-like colony.
Yeast
What is the mode of reproduction for yeast?
Budding
These are multicellular vegetative cell that has a fuzzy or wholly appearance.
Molds
What causes the appearance of molds?
Mycelia
Identify the part of hyphae:
Extends beyond the surface.
Aerial mycelia
These are long strands of tube-like structures that composes the mycelium (mycelia).
Hyphae
Identify the part of hyphae:
Extend downward.
Vegetative mycelia
Identify the part of hyphae:
Support reproductive structures that produces conidia.
Aerial mycelia
Identify the part of hyphae:
Absorb water and nutrients.
Vegetative mycelia
What type of hyphae has frequent cross walls?
Septate hyphae
What type of hyphae has few cross walls with irregular intervals?
Sparsely septate hyphae
What do you call the absence of septations?
Aseptate (actually: sparsely septate)
