Question 1

Which of the following is a derived trait found in all land plants but absent in charophytes?

Accepted Answer

Alternation of generations

Question 2

In the haplodiplontic life cycle of plants, what process directly produces haploid spores from the diploid sporophyte?

Accepted Answer

Meiosis

Question 3

Which adaptation allowed plants to minimize water loss when colonizing land?

Accepted Answer

Waxy cuticle covering the epidermis

Question 4

What is the dominant life stage in mosses (Phylum Bryophyta)?

Accepted Answer

Gametophyte

Question 5

Which structure in mosses is responsible for producing sperm?

Accepted Answer

Antheridia

Question 6

Why are bryophytes (nonvascular plants) typically limited to moist environments?

Accepted Answer

They rely on diffusion and need water for sperm to swim to the egg

Question 7

Which of the following best describes the relationship between the sporophyte and gametophyte in mosses?

Accepted Answer

The sporophyte grows out of and depends on the gametophyte for nutrition

Question 8

Which equation correctly represents the transition from gametophyte to sporophyte in the plant life cycle?

Accepted Answer

$$n \xrightarrow{fertilization} 2n$$

Question 9

Which of the following is NOT a function of apical meristems in plants?

Accepted Answer

Producing multicellular gametangia

Question 10

A botanist discovers a small, nonvascular plant with scale-like leaves and rhizoids. Which group does this plant most likely belong to?

Accepted Answer

Bryophytes

Question 11

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

Accepted Answer

The gametophyte produces gametes by mitosis

Question 12

Which adaptation helps plants deal with increased UV radiation on land?

Accepted Answer

Shift to a dominant diploid generation

Question 13

What is the primary function of the sporangium in mosses?

Accepted Answer

Producing and releasing haploid spores

Question 14

Which of the following is true about the life cycle of mosses?

Accepted Answer

The gametophyte is the dominant, photosynthetic stage

Question 15

Which group of plants is characterized by having seeds but lacking flowers?

Accepted Answer

Gymnosperms

Question 16

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

Accepted Answer

Sporophyte $$\rightarrow$$ meiosis $$\rightarrow$$ spore $$\rightarrow$$ mitosis $$\rightarrow$$ gametophyte

Question 17

Which of the following is NOT a characteristic of nonvascular plants?

Accepted Answer

Presence of true roots, stems, and leaves

Question 18

In flowering plants, where is the female gametophyte located?

Accepted Answer

Buried within the tissues of the sporophyte

Question 19

Which of the following best explains why natural selection can act differently on the sporophyte and gametophyte stages in plants?

Accepted Answer

Each stage is multicellular and may live in different environments

Question 20

Which of the following plant groups contains the largest number of known species?

Accepted Answer

Phylum Anthophyta (Flowering plants)
