$$\text{Glucose} \rightarrow \text{Glycogen}$$

Question 1

Which of the following best describes the mode of nutrient acquisition in fungi?

Accepted Answer

Fungi are heterotrophs that absorb nutrients after excreting hydrolytic enzymes.

Question 2

What is the primary structural component of fungal cell walls?

Accepted Answer

Chitin

Question 3

Which stage in the fungal sexual life cycle involves the fusion of cytoplasm but not nuclei?

Accepted Answer

Plasmogamy

Question 4

A mass of hyphae in a fungus is called:

Accepted Answer

Mycelium

Question 5

Which group of fungi is unique for producing flagellated spores called zoospores?

Accepted Answer

Chytrids

Question 6

Why is the loss of flagellated sperm/spores considered advantageous for later diverged fungal species?

Accepted Answer

It enabled fungi to disperse spores through air, increasing terrestrial diversity.

Question 7

Which equation best represents the process of meiosis in fungal sexual reproduction?

Accepted Answer

$$2n \rightarrow n$$

Question 8

Which type of symbiotic relationship is exemplified by mycorrhizal fungi and plants?

Accepted Answer

Mutualism

Question 9

Which of the following is a key difference between fungal and plant life cycles?

Accepted Answer

Fungi have a heterokaryotic stage, plants do not.

Question 10

Which structure is produced during asexual reproduction in filamentous fungi?

Accepted Answer

Conidia

Question 11

A fungal infection causing athlete’s foot is an example of which ecological role?

Accepted Answer

Pathogen

Question 12

Which equation best represents the fusion of nuclei during fungal sexual reproduction?

Accepted Answer

$$n + n \rightarrow 2n$$

Question 13

Which group of fungi forms a mutualistic relationship with most plants, aiding in nutrient uptake?

Accepted Answer

Glomeromycetes

Question 14

Which of the following is NOT a plausible consequence of fungi lacking septa in their hyphae?

Accepted Answer

Restricted movement of organelles

Question 15

Which equation best represents the storage of glucose in fungi?

Accepted Answer

$$	ext{Glucose} ightarrow 	ext{Glycogen}$$

Question 16

Which of the following best explains the economic importance of fungi in agriculture?

Accepted Answer

Fungi can both enhance plant growth and cause crop diseases.

Question 17

Which of the following is a plausible reason why fungi are more closely related to animals than plants?

Accepted Answer

Both synthesize chitin and store glucose as glycogen.

Question 18

Which of the following is a real-world example of a mutualistic fungal relationship?

Accepted Answer

Lichen formation between fungi and algae

Question 19

Which of the following best describes the heterokaryotic stage in fungal reproduction?

Accepted Answer

Cells contain nuclei from different parents that have not fused.

Question 20

Which of the following is a plausible effect of removing mycorrhizal fungi from agricultural soil?

Accepted Answer

Plant growth would be greatly slowed due to reduced nutrient uptake.
