FAQs on Double Fertilisation

Question 1

1. What is sexual reproduction in flowering plants?

Accepted Answer

Ans. Sexual reproduction in flowering plants involves the fusion of male and female gametes to produce offspring. This process typically occurs through the formation of flowers, which contain reproductive organs such as the stamen (male) and pistil (female).

Question 2

2. How do flowering plants reproduce sexually?

Accepted Answer

Ans. Flowering plants reproduce sexually through a process called pollination, where pollen from the male reproductive organs (anther) is transferred to the female reproductive organs (stigma) of the same or different plant. This leads to fertilization and the formation of seeds.

Question 3

3. What are the advantages of sexual reproduction in flowering plants?

Accepted Answer

Ans. Sexual reproduction in flowering plants leads to genetic variation, which helps in adaptation to changing environments and increases the chances of survival. It also allows for the exchange of genetic material between different individuals, leading to offspring with diverse traits.

Question 4

4. What are the different methods of pollination in flowering plants?

Accepted Answer

Ans. Pollination in flowering plants can occur through self-pollination, where pollen is transferred to the stigma of the same flower or plant, or cross-pollination, where pollen is transferred between different plants. This can be achieved through wind, water, insects, birds, or other animals.

Question 5

5. How do seeds develop in flowering plants after fertilization?

Accepted Answer

Ans. After fertilization, the ovule develops into a seed within the ovary of the flower. The ovary then matures into a fruit, which protects and aids in the dispersal of the seeds. The seeds contain the genetic material necessary for the development of a new plant.
