Diploid

Question 14

Which of the following correctly matches the fungal phylum with its sexual spore-producing structure?

Accepted Answer

Ascomycota – Ascus

Question 15

A fungal hypha is described as dikaryotic. What does this mean?

Accepted Answer

It contains two genetically distinct haploid nuclei per cell.

Question 16

Which event restores the diploid state in the fungal sexual life cycle?

Accepted Answer

Karyogamy

Question 17

In a real-world scenario, a bread mold (Mucoromycota) is observed producing spores on stalks. Which structure is being observed?

Accepted Answer

Sporangiophore

Question 18

Which process leads to the formation of genetically diverse spores in fungi?

Accepted Answer

Meiosis

Question 19

A scientist isolates a fungus and observes that all components involved in its asexual reproduction are haploid. Which statement best explains this observation?

Accepted Answer

Asexual reproduction in fungi typically involves haploid cells and structures.

Question 20

Which sequence correctly describes the order of major events in the sexual life cycle of fungi?

Accepted Answer
