Question 2

The transition from aquatic to terrestrial life in plants required adaptations to prevent desiccation. Which molecule is primarily responsible for protecting plant zygotes and spores from drying out?

Accepted Answer

Sporopollenin

Question 3

In the alternation of generations, which process results in the formation of haploid spores from a diploid sporophyte?

Accepted Answer

Meiosis

Question 4

Referencing the diagram of alternation of generations, what is the ploidy of the zygote immediately after fertilization?

Accepted Answer

Diploid ($$2n)$$

Question 5

Which structure in bryophytes anchors the plant to the substrate but does not absorb water or nutrients?

Accepted Answer

Rhizoid

Question 6

Based on the nitrogen loss graph, what ecological role do mosses play in terrestrial ecosystems?

Reduce nitrogen loss from soil

Question 7

Peat moss (Sphagnum) is important in the preservation of organic remains in peatlands. Which property of peatlands contributes most to this preservation?

Accepted Answer

Low decomposition rates

Question 8

Which of the following is a derived trait of land plants that enables growth and exploration of new environments?

Apical meristems

Question 9

Which group of plants is characterized by the presence of microphylls, as shown in the leaf comparison diagram?

Accepted Answer

Lycophytes

Question 10

In seedless vascular plants, which tissue is responsible for transporting water and minerals from roots to leaves?

Accepted Answer

Xylem

Question 11

Which plant group has a life cycle dominated by the gametophyte stage?

Accepted Answer

Bryophytes

Question 12

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

Accepted Answer

Alternation between multicellular haploid gametophyte and multicellular diploid sporophyte

Question 13

Which of the following is NOT a function of the cuticle in land plants?

Accepted Answer

Providing structural support

Question 14

Which of the following statements about the sporophyte in bryophytes is correct?

Accepted Answer

It remains attached to and dependent on the gametophyte

Question 15

Which of the following is a real-world application of peat moss (Sphagnum)?

Accepted Answer

Used as fuel and for soil conditioning

Question 16

Which of the following best explains why seedless vascular plants were able to grow taller than bryophytes?

Accepted Answer

Presence of vascular tissues for support and transport

Question 17

Which of the following is a characteristic of hornworts that distinguishes them from other bryophytes?

Accepted Answer

Sporophytes are horn-shaped and grow from the gametophyte

Question 18

Which of the following equations correctly represents the process of fertilization in the plant life cycle?

Accepted Answer

$$n + n \rightarrow 2n$$

Question 19

Which of the following is true about the vascular tissue arrangement in microphylls versus megaphylls?

Accepted Answer

Microphylls have unbranched vascular tissue; megaphylls have branched vascular tissue

Question 20

Which of the following plant groups is classified as seedless vascular plants?

Accepted Answer
