Question

Define Pollination .

Name two types of pollination and define them .​

Answer 1

Pollination : The term pollination refers to the process of transfer of pollen grains from anther and their deposition on to the stigmatic surface of the flower.

Two types of pollination are :

•Self pollination

•Cross pollination

Self pollination : Self pollination is the transfer of the pollen grains from the anther to the stigma of either same or genetically similar flower.

Cross pollination : Cross pollination is defined as the deposition of pollen grains from anther to stigma of a different or another plant of same or different species .

Answer 2

Pollination: The transfer of pollen grains from another to the stigma of the flower is called as pollination.

Two main types of pollination are:

1. self pollination:-

Self-pollination is a type of pollination which occurs in a single flower or two flowers on a single plant.

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \large{or}$

It is the transfer of pollen grains from anther to the stigma of the same flower or a different flower produced on the same plant.

2. cross pollination:-

It is the transfer of pollen grains from the anther of one flower to the stigma of another flower of different plants of same species.

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \large{or}$

It is the transfer of pollen grains from anther of a flower to the stigma of another flower produced on a different plant having dissimilar genetic make-up, with the help of external agents like wind, water, insects, etc.
