Question:

How is the process of pollination different from fertilisation?

Answer:

Pollination:- Transfer of pollen grain from the anther (male part of the flower) of stamen to the stigma (female part of the flower) of carpel is known as pollination. It is of two types:-

  1. Self pollination:- It involves the transfer of pollen grains from the anther to the stigma of the same flower or genetically similar flower.

  2. Cross pollination:- It involves the transfer of pollen grains from the flower of one plant to the stigma of the flower of another plant.

Transfer of pollen grains can be occur through many agents like anemophily (wind pollination), hydrophily (water pollination), entomophily (insect pollination), ornithophily (pollination by birds) and chiropterophily (bat pollination). 

Fertilisation:- Fusion of haploid male gamete (spermatozoan) and a haploid female gamete (ovum) and they together forms a diploid cell, i.e, zygote is known as fertilisation.
