Question

Distinguish between pollination and fertilisation. Mention the site and product of fertilisation in a flower.

Draw a neat, labelled diagram of a pistil showing pollen tube growth and its entry into the ovule.

Answer 1

Pollination	Fertilization
It is the process of transfer of pollen grains from the anther to the stigma of the pistil of the flower.	It is the process of fusion of male and female gametes resulting in the formation of zygote.
This process leads to fertilization.	This process leads to formation of seeds.
Pollen tube formation does not take place in pollination.	After pollination, pollen tube forms for fertilization to occur.
Pollination occurs in flowering plants.	Fertilization occurs in every living beings which undergo sexual reproduction.

The site of fertilisation in the flower is the ovule present in the ovary.
The product of fertilisation of male and female gamete is the zygote.
