Question

Explain the process of fertilization in plants which lead to formation of zygote.

Answer 1

Fertilization is the process of fusion of male and female gamete to form zygote.

• The male reproductive organ is anther which produces pollen grains. Pollen grains contain the male gamete in them.
• The female reproductive organ is ovary which produces the female gamete.
• The pollen grains are transferred to the stigma of the female reproductive part through pollination.
• Pollen grains then produce a pollen tube and transfer male gametes to the ovary.
• Inside the ovary, the male gamete fuses with the female gamete to form zygote.
