Which statement about the daughter cells following mitosis and cytokinesis is correct? a. They are genetically different from each other and from the parent cell. b. They are genetically identical to each other and to the parent cell. c. They are genetically identical to each other but different from the parent cell. d. Only one of the two daughter cells is genetically identical to the parent cell.

The mycelial growth habit leads to a body with a high surface-area-to-volume ratio. Why is this important? a. Mycelia have a large surface area for absorption. b. The hyphae that make up mycelia are long, thin tubes. c. Most hyphae are broken up into compartments by walls called septa, although some exist as single, gigantic cells. d. Hyphae can infiltrate living or dead tissues.

Evaluate the following statements about mushrooms. Select True or False for each statement.

T/F A diploid zygote is formed when a male spore fertilizes a female spore.

T/F Haploid spores are formed by meiosis in basidia.

T/F A mushroom is a reproductive structure that consists largely of dikaryotic cells.

T/F Mushrooms are part of the group that also includes bracket fungi, boletes, puffballs, and stinkhorns.

The hyphae of arbuscular mycorrhizal fungi (AMF) form bushy structures after making contact with the plasma membrane of a root cell. What is the function of these structures?

a. They anchor the fungus inside the root, so the association is more permanent.

b. They increase the surface area available for the transfer of nutrients.

c. They produce toxins that protect the plant cells against herbivores.

d. They break down cellulose and lignin in the plant cell wall.

What does it mean to say that a hypha is dikaryotic?

a. Two nuclei fuse during sexual reproduction to form a zygote.

b. Two independent nuclei, derived from different individuals, are present in each cell.

c. The nucleus is diploid or polyploid — not haploid.

d. It is extremely highly branched, which increases its surface area and thus absorptive capacity.
