Question

Explain the process of fertilization.

Answer 1

After pollination, the pollen grains in the stigma start to grow, absorbing the nutrients from the stigma. A thin tube called pollen tube, starts growing out of the pollen grains till it reaches the ovary and enters the ovule. This tube carries the male gamete which is released into the ovule containing female gametes. There the male and female gametes unite together to form zygote. This process is called fertilization.
