When yeast are grown on agar, which of the following best describes the appearance of their colonies?
A
Dry, rough, and filamentous colonies
B
Transparent, spreading colonies
C
Smooth, moist, and creamy colonies
D
Green, fuzzy colonies
Verified step by step guidance1
Understand that yeast are unicellular fungi, and their colony morphology on agar reflects their biological characteristics.
Recall that yeast colonies typically appear different from bacterial or mold colonies; molds often produce filamentous or fuzzy colonies due to hyphae growth.
Recognize that yeast colonies are generally smooth because they grow as single cells that bud, leading to a uniform surface.
Note that yeast colonies tend to be moist and creamy in texture, which distinguishes them from dry or rough bacterial colonies and fuzzy mold colonies.
Conclude that the best description of yeast colonies on agar is 'Smooth, moist, and creamy colonies' based on their cellular structure and growth pattern.
