Final answer:
Yeasts are unicellular fungi that reproduce by budding, while molds are multicellular fungi that form hyphae.
Step-by-step explanation:
Yeasts and molds are both types of fungi, but they have some key differences.
Yeasts are unicellular fungi that reproduce asexually by budding off a smaller daughter cell. They are typically spherical in shape and around 5 um in diameter. Yeasts have beneficial uses such as causing bread to rise and beverages to ferment, but some can also cause diseases like vaginal yeast infections and oral thrush.
Molds are multicellular fungi that form hyphae. These hyphae may be septate or nonseptate. Unlike yeasts, molds can sometimes form visible colonies that are furry, fuzzy, or powdery. Molds are commonly found on food and can cause spoilage.
