Question

What is pollination? How does it lead to fertilization? Explain with the help of a diagram.

Answer 1

Pollination is the process of transfer of pollen grains from the anthers to the stigma. After reaching the stigma, pollen grain starts to grow. A thin tube called the pollen tube grows down from the pollen grain through the pistil. The pollen tube carries the male cell. It grows and enters the ovule. The male cell moves into the ovule and fuses with the egg to form zygote. The fusion of male cell with the egg is called fertilisation.
