Question 1

Which of the following is a key difference between fungi and plants?

Accepted Answer

Fungi have cell walls made of chitin, while plants have cell walls made of cellulose.

Question 2

A scientist discovers a multicellular organism with hyphae, chitin cell walls, and no chloroplasts. Which kingdom does this organism most likely belong to?

Accepted Answer

Fungi

Question 3

Which fungal phylum is primarily aquatic and produces flagellated spores?

Accepted Answer

Chytridiomycota

Question 4

Which of the following best describes the ecological role of fungi in an ecosystem?

Accepted Answer

Decomposers breaking down organic material and recycling nutrients

Question 5

Which statement about the fungal life cycle is correct?

Accepted Answer

Fungi can be haploid, diploid, or dikaryotic ($$n+n) $$during their life cycle.

Question 6

A plant is described as multicellular, eukaryotic, and having cell walls made of cellulose. Which organelle is essential for its photoautotrophic lifestyle?

Accepted Answer

Chloroplast

Question 7

Which of the following is a disadvantage for plants colonizing land?

Accepted Answer

Desiccation due to exposure to air

Question 8

Which process in plants promotes outcrossing and genetic diversity?

Accepted Answer

Production of spores by meiosis

Question 9

Which of the following best describes the alternation of generations in plants?

Accepted Answer

Multicellular diploid (2n) and haploid (n) phases alternate, with spores produced by meiosis.

Question 10

Which of the following is a characteristic of angiosperms but not gymnosperms?

Accepted Answer

Seeds enclosed in fruit

Question 11

Which of the following is true about the structure of a virus?

Accepted Answer

Viruses have a genome, capsid, and sometimes a lipid envelope.

Question 12

Which statement best explains why viruses are not considered living organisms?

Accepted Answer

Viruses cannot carry out metabolism or reproduce independently.

Question 13

Which of the following is a correct comparison between RNA and DNA viruses?

Accepted Answer

RNA viruses generally mutate more rapidly than DNA viruses.

Question 14

Which of the following is a consequence of herd immunity?

Accepted Answer

It reduces the spread of infectious diseases in a population.

Question 15

Which of the following is a valid reason why some zoonotic diseases are difficult to eradicate?

Accepted Answer

They have non-human animal reservoirs that can reintroduce the disease to humans.

Question 16

Which of the following is NOT a function of viruses?

Accepted Answer

Production of ATP

Question 17

Which of the following best describes the process of double fertilization in angiosperms?

Accepted Answer

One sperm fertilizes the egg, and another sperm fertilizes the central cell to form endosperm.

Question 18

Which of the following is a major advantage of seeds in plant evolution?

Accepted Answer

Seeds allow plants to resist desiccation and remain dormant until conditions are favorable.

Question 19

Which of the following is a correct statement about the Baltimore classification of viruses?

Accepted Answer

It groups viruses based on their genome type and replication strategy.

Question 20

A population of plants has a sporophyte generation that produces spores by meiosis. If the sporophyte is diploid ($$2n$$), what is the ploidy of the spores?

Accepted Answer

Haploid ($$n)$$
