Question 1

Which of the following is NOT a trait shared by both charophytes and land plants?

Accepted Answer

Presence of apical meristems

Question 2

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

Accepted Answer

A multicellular haploid gametophyte produces gametes by mitosis, which fuse to form a diploid zygote that grows into a multicellular diploid sporophyte.

Question 3

In the bryophyte life cycle, which structure is responsible for producing haploid spores?

Accepted Answer

Sporangium of the sporophyte

Question 4

Which of the following best distinguishes xylem from phloem?

Accepted Answer

Xylem transports water and minerals upward; phloem transports sugars in multiple directions.

Question 5

Which of the following is a key advantage of the reduced gametophyte in seed plants?

Accepted Answer

It is protected from environmental stresses within the tissues of the sporophyte.

Question 6

Which of the following correctly matches the plant group with its dominant generation?

Accepted Answer

Bryophytes: gametophyte dominant

Question 7

A botanist discovers a plant with vascular tissue, seeds, but no flowers. To which group does this plant most likely belong?

Accepted Answer

Gymnosperms

Question 8

Which of the following best describes double fertilization in angiosperms?

Accepted Answer

One sperm fertilizes the egg, and another sperm fertilizes the central cell, forming a triploid endosperm.

Question 9

Which of the following is a derived trait of seed plants that is NOT found in seedless vascular plants?

Accepted Answer

Production of pollen

Question 10

A plant with parallel leaf veins, scattered vascular bundles in the stem, and a fibrous root system is most likely a:

Accepted Answer

Monocot

Question 11

Which of the following best describes the function of the vascular cambium in woody plants?

Accepted Answer

It produces secondary xylem and secondary phloem, contributing to the plant's increase in thickness.

Question 12

Which of the following is true regarding the anatomy of a tree trunk?

Accepted Answer

The bark consists of all tissues external to the vascular cambium, including secondary phloem and periderm.

Question 13

Which of the following is a correct comparison between simple and compound leaves?

Accepted Answer

A simple leaf has a single, undivided blade, while a compound leaf has a blade divided into multiple leaflets.

Question 14

Which of the following cell types is specialized for photosynthesis in leaves?

Accepted Answer

Parenchyma cells

Question 15

A plant is observed to have a taproot system, netlike leaf veins, and vascular bundles arranged in a ring in the stem. This plant is most likely a:

Accepted Answer

Eudicot

Question 16

Which of the following best describes the difference between primary and secondary growth in plants?

Accepted Answer

Primary growth increases length; secondary growth increases thickness.

Question 17

Which of the following structures is diploid in the angiosperm life cycle?

Accepted Answer

Sporophyte

Question 18

Which of the following is a correct statement about homosporous and heterosporous plants?

Accepted Answer

Heterosporous plants produce both megaspores and microspores; homosporous plants produce only one type of spore.

Question 19

Which of the following is a function of root hairs?

Accepted Answer

Increase surface area for water and mineral absorption

Question 20

Which of the following best describes the difference between archegonia and antheridia?

Accepted Answer

Archegonia produce eggs; antheridia produce sperm.
