Reproduction in Plants
Q. What is the primary function of flowers in angiosperms?
-
A.
Photosynthesis
-
B.
Reproduction
-
C.
Water absorption
-
D.
Nutrient storage
Solution
Flowers are the reproductive structures of angiosperms, facilitating pollination and seed production.
Correct Answer: B — Reproduction
Q. What is the role of the ovule in plant reproduction?
-
A.
To produce pollen
-
B.
To develop into a seed after fertilization
-
C.
To attract pollinators
-
D.
To support the flower structure
Solution
The ovule develops into a seed after fertilization, containing the embryo and food supply.
Correct Answer: B — To develop into a seed after fertilization
Q. What is the term for plants that can reproduce without fertilization?
-
A.
Autotrophs
-
B.
Apomicts
-
C.
Heterotrophs
-
D.
Monocots
Solution
Apomicts are plants that can produce seeds without fertilization, resulting in offspring that are genetically identical to the parent.
Correct Answer: B — Apomicts
Q. Which of the following is NOT a method of seed dispersal?
-
A.
Wind
-
B.
Water
-
C.
Animal ingestion
-
D.
Photosynthesis
Solution
Photosynthesis is not a method of seed dispersal; it is the process by which plants convert light energy into chemical energy.
Correct Answer: D — Photosynthesis

Stigma
-
B.
Style
-
C.

D.
Petal
Solution
The pistil, which includes the stigma, style, and ovary, is responsible for receiving pollen during pollination.
Correct Answer: B — Pistil
Q. Which type of pollination occurs when pollen is transferred from one flower to another of the same species?
-
A.
Self-pollination
-
B.
Cross-pollination
-
C.
Wind pollination
-
D.
Water pollination
Solution
Cross-pollination involves the transfer of pollen between different flowers of the same species, promoting genetic diversity.
Correct Answer: B — Cross-pollination
