In the life cycle of land plants, which structure is produced by meiosis?

Accepted Answer

Haploid spores

Question 3

Which equation correctly represents the change in chromosome number during meiosis in land plants?

Accepted Answer

$$2N \rightarrow N$$

Question 4

A botanist discovers a plant with a dominant gametophyte and a dependent sporophyte. Which group does this plant most likely belong to?

Accepted Answer

Bryophytes (mosses, liverworts, hornworts)

Question 5

Which adaptation allowed early land plants to prevent desiccation and survive in terrestrial environments?

Accepted Answer

Production of spores with sporopollenin walls

Question 6

Which of the following statements about the alternation of generations in land plants is correct?

Accepted Answer

The sporophyte produces spores by meiosis

Question 7

Which structure in mosses is responsible for anchorage and absorption of water and nutrients?

Accepted Answer

Rhizoids

Question 8

A student is examining a plant specimen and observes multicellular sporangia and multicellular gametangia. What does this indicate about the specimen?

Accepted Answer

It is a land plant (embryophyte)

Question 9

Which of the following best describes the evolutionary relationship between green algae and land plants?

Accepted Answer

Charophytes are the closest relatives to land plants

Question 10

Which equation represents the chromosome number change during fertilization in the plant life cycle?

Accepted Answer

$$N + N \rightarrow 2N$$

Question 11

Which of the following is NOT a derived trait of land plants?

Accepted Answer

Unicellular gametangia

Question 12

A plant has a multicellular embryo retained within the tissue of the female parent. What is the significance of this feature?

Accepted Answer

It protects the embryo from harsh environmental conditions

Question 13

Which of the following groups is characterized by the absence of vascular tissue, seeds, and flowers?

Accepted Answer

Bryophytes (mosses, liverworts, hornworts)

Question 14

Which structure in mosses is responsible for spore production?

Accepted Answer

Capsule

Question 15

Which of the following best explains why spores and gametes in land plants are both haploid?

Accepted Answer

Spores are produced by meiosis, gametes by mitosis

Question 16

Which of the following is a correct sequence of events in the life cycle of a liverwort?

Accepted Answer

Gametophyte (n) produces gametes → fertilization → sporophyte (2n) produces spores → spores grow into gametophyte

Question 17

Which of the following is a function of the archegonia in liverworts?

Accepted Answer

Production of eggs

Question 18

Which of the following statements about the phylogeny of land plants is correct?

Accepted Answer

Liverworts, mosses, and hornworts are each monophyletic lineages

Question 19

Which of the following best describes the role of sporopollenin in the evolution of land plants?

Accepted Answer

It forms a protective wall around spores, preventing desiccation

Question 20

A scientist finds a fossilized spore embedded in plant-like tissue dating back 470 million years. What does this suggest about the evolution of land plants?

Accepted Answer

Land plants evolved before the development of seeds and flowers
