Option 1 : A, E
The correct answer is A, E.
Concept:
- Pollination: The process of transfer of pollen (from male reproductive part i.e. anther) to the stigma (from female reproductive part i.e. carpel) of flowering plants is called Pollination.
- Fertilization: It is the fusion of male and female gamete.
Explanation:
A. Ovary of the flower matures into fruit. (True)
- The ovary is a part of the pistil, the female reproductive structure of the flower. Ovules are found inside the ovary.
- After the fertilization, the ovary matures to form fruit.
- Fruits can be:
- Fleshy, e.g., orange, mango, etc.
- Dry, e.g., mustard, groundnut, etc.
B. Seeds of the plant form the ovules for fertilization. (False)
- Plant seeds do not produce ovules for fertilisation; rather, the ovules develop into seeds that contain an embryo and an endosperm.
- A seed is formed when a fertilised ovule divides through mitosis. It stores food and has the potential to develop into a new plant under ideal conditions.
C. Pollination takes place after fertilization. (False)
- Fertilization takes place after pollination because after the pollination process, i.e. once the pollen grain reaches the stigma, fertilization occurs by fusing male gamete and female gamete.
D. In pollination, seeds are dispersed by wind, water, birds and insects. (False)
- Seeds is a fertilised ovule which is the final product of the sexual reproduction.
- In pollination, pollen grains are dispersed by wind, water, birds, and insects not the seeds.
- Agents of pollination
- Abiotic agents: Wind, water
- Biotic agents: Animals
- The form of pollination in which pollens are distributed by water is called hydrophilly.
- The form of pollination in which wind distributes the pollens is called anemophily.
- The form of pollination in which insects distributes the pollens is called entomophily.
E. Fertilisation takes places in the ovules. (True)
- Fertilization occurs when a sperm cell fuses with an egg cell within an ovule.
- Each ovule develops into a seed after fertilization.
