Question

The process of fusion of the male and the female gametes is called
A. Fertilisation
B. Pollination
C. Reproduction
D. Seed formation

Answer 1

Hint: In sexual reproducing organisms, fusion of male and female gametes occurs in the female reproductive system. It involves intermixing of genetic material.

Complete step by step answer:
To solve the question we must know about the gametes and fusion of it.
There are two types of gametes-male and female gametes. The male gametes enter the female body. The female gametes or the ovum fuses with the male gametes to form a diploid zygote. This process is called fertilisation. It occurs in the body of the female. The zygote further develops into an embryo. It is an important step in reproduction.
Pollination- It is the process of transferring pollen grains from the anther to the stigma in flowers.
Reproduction- It is the process by which a new individual or off-spring is formed from the parent.
Seed Formation- It is formed after the fertilised zygote divides by mitosis. It is the end product of reproduction in plants. It stores food and can grow into a new plant under favourable conditions.

Thus the correct answer is A. Fertilisation is the fusion of male and female gametes.

Additional Information: After fertilisation, all the other parts of the flower sheds except the ovary which develops into the fruit and the ovules develop into the seeds. The growing embryo develops and matures inside the seed.

Note:
The fusion of male and female gametes is an important step of reproduction. The fusion results in formation of zygote which on further cell division and maturation grows into an embryo then an off-spring.
