Question 1

What are the common characteristics of fungi?

Answer 1

1. Eukaryotic
2. Unicellular reproduction via sporulation
3. Heterotrophic
4. Cell walls made of chitin
5. Grow hyphae
6. Ergosterol in cell membranes

Question 2

What are the common characteristics of yeasts?

Answer 2

1. Unicellular

2. Do not use hyphae for nutrient accumulation

Question 3

How do yeasts reproduce?
