Practice Set
The second half of our 100-question series for Module 2. This 2026 update focuses
on Dermal/Ground/Vascular Tissues, Primary vs. Secondary Growth, Flower Symmetry,
and Seed Dispersal Mechanisms. Essential for students mastering the complexities of modern
flowering plants and their evolutionary success.
1. Which group of green algae is the closest relative to land plants?
A. Chlorophytes
B. Charophytes
C. Rhodophytes
D. Phaeophytes
Rationale: Charophytes share unique structural and biochemical traits
with land plants, such as cellulose-synthesizing proteins.
2. In the "Alternation of Generations," the haploid multicellular stage
is the:
A. Sporophyte
B. Gametophyte
C. Zygote
D. Spore
Rationale: The Gametophyte (n) produces gametes via mitosis.
3. Which of the following is a "Non-vascular" plant (Bryophyte)?
A. Fern
B. Moss
C. Pine Tree
D. Rose
Rationale: Mosses lack specialized vascular tissues (xylem/phloem) and
true roots.
4. What is the primary function of "Xylem"?
A. Transporting sugar
B. Transporting water and minerals upward
C. Photosynthesis
D. Seed protection
Rationale: Xylem moves water from roots to shoots and is reinforced with
lignin.
,5. Which plant group was the first to develop "True Roots" and
"Leaves"?
A. Bryophytes
B. Seedless Vascular Plants (Ferns)
C. Gymnosperms
D. Angiosperms
Rationale: Ferns and their relatives evolved vascular tissue, allowing for
complex organ structures.
6. In Bryophytes, which generation is "Dominant"?
A. Sporophyte
B. Gametophyte
C. Both are equal
D. Neither
Rationale: In Mosses, the green, leafy plant is the haploid gametophyte;
the sporophyte grows out of it.
7. "Stomata" are essential for land plants because they:
A. Absorb soil water
B. Allow gas exchange and control water loss
C. Produce pollen
D. Anchor the plant
Rationale: Stomata are regulated pores on the leaf surface.
8. Which of the following is an example of a "Gymnosperm"?
A. Oak Tree
B. Pine Tree (Conifer)
C. Fern
D. Moss
Rationale: Gymnosperms have "naked seeds" typically housed in cones.
9. "Angiosperms" are distinguished by the presence of:
A. Seeds
B. Vascular tissue
C. Flowers and Fruits
D. Flagellated sperm
Rationale: Flowers facilitate pollination, and Fruits aid in seed dispersal.
10. What is the role of "Phloem"?
A. Moving water
B. Transporting organic nutrients (sugars)
, C. Making spores
D. Protecting embryos
Rationale: Phloem carries the products of photosynthesis to where they
are needed.
11. "Lignin" allows plants to:
A. Photosynthesize faster
B. Grow tall by providing structural support
C. Attract bees
D. Survive in salt
Rationale: Lignin hardens the cell walls of vascular tissue.
12. "Sporopollenin" is found in the walls of:
A. Roots
B. Spores and Pollen grains
C. Leaves
D. Seeds
Rationale: This polymer prevents desiccation (drying out) of reproductive
cells.
13. Which of the following is a "Seedless Vascular" plant?
A. Liverwort
B. Fern
C. Ginkgo
D. Lily
Rationale: Ferns have vascular tissue but reproduce via spores, not
seeds.
14. In Seed Plants, the "Dominant" generation is the:
A. Gametophyte
B. Sporophyte
C. Zygote
D. Archegonia
Rationale: The Sporophyte (2n) is the prominent, independent stage in
gymnosperms and angiosperms.
15. "Apical Meristems" are regions of:
A. Dead tissue
B. Active cell division at root and shoot tips
C. Seed storage
