Q: Which of the following equations best represents the process of absorptive nutrition in fungi?

$$\text{Enzymes} + \text{Large Organic Molecules} \rightarrow \text{Small Organic Molecules}$$

Question 1

Which of the following is a major characteristic that distinguishes fungi from plants?

Accepted Answer

Fungi are heterotrophic and use absorptive nutrition.

Question 2

Fungi and animals share several characteristics. Which of the following is a trait shared by both groups?

Accepted Answer

Both store surplus food as glycogen.

Question 3

Which structure in fungi is primarily responsible for nutrient absorption?

Accepted Answer

Hyphae

Question 4

During the sexual life cycle of fungi, at which stage are the cells typically diploid?

Accepted Answer

During the formation of the zygote, before meiosis

Question 5

Which of the following best describes the growth pattern of fungal mycelia?

Accepted Answer

Growth occurs at the edges, resulting in extensive branching and high surface area.

Question 6

What is the ecological role of mycorrhizal fungi in terrestrial ecosystems?

Accepted Answer

They form mutualistic associations with plant roots, enhancing water and mineral uptake.

Question 7

Which of the following terms describes a fungal cell or mycelium containing two genetically distinct nuclei per cell?

Accepted Answer

Dikaryotic

Question 8

A scientist discovers a fungus that forms a mutualistic relationship with cyanobacteria, resulting in a composite organism. What is this organism called?

Accepted Answer

Lichen

Question 9

Which process is essential for the extension of fungal hyphae at their tips?

Accepted Answer

Osmosis, allowing water entry and tip extension

Question 10

Which of the following best explains why fungi cannot engulf food particles?

Accepted Answer

Their tough cell walls made of chitin restrict mobility and engulfment.

Question 11

A patient with AIDS develops pneumonia caused by a fungus. Which type of fungus is most likely responsible?

Accepted Answer

Pneumocystis carinii

Question 12

Which of the following equations best represents the process of absorptive nutrition in fungi?

Accepted Answer

$$	ext{Enzymes} + 	ext{Large Organic Molecules} ightarrow 	ext{Small Organic Molecules}$$

Question 13

Which of the following is NOT a role played by fungi in biotechnology?

Accepted Answer

Synthesis of cellulose for plant cell walls

Question 14

A fungal fruiting body produces hallucinogenic substances. What is the most likely consequence for humans who consume it?

Accepted Answer

Liver failure requiring a transplant

Question 15

Which of the following best describes the relationship between fungi and animals in the supergroup Opisthokonta?

Accepted Answer

Fungi and animals share a common ancestor and are more closely related to each other than to plants.

Question 16

Which of the following is a correct sequence of events in the sexual reproduction of fungi?

Accepted Answer

Fusion of hyphae → Formation of dikaryotic mycelium → Nuclear fusion → Meiosis → Spore production

Question 17

Which of the following is true about decomposing fungi?

Accepted Answer

They release minerals and nutrients into the soil and water, aiding ecosystem nutrient cycling.

Question 18

A fungus traps tiny soil nematodes and digests them. What type of ecological role does this fungus play?

Accepted Answer

Predator

Question 19

Which of the following best describes the function of the fruiting body in fungi?

Accepted Answer

Producing and dispersing spores for reproduction

Question 20

Which of the following is the correct definition of 'mycelium'?

Accepted Answer

A network of hyphae that forms the main body of a fungus
