Answers
POLLINATION is the process of transfer of pollen grain from anther to stigma of same flower or different flower of same type.
It is of two type :-
- SELF- POLLINATION = Transfer of pollen grain from ANTHER to STIGMA of same flower.
- CROSS- POLLINATION = Transfer of pollen grain from ANTHER to STIGMA of different flower but of same type.
Answer:
The transfer of pollen grains from the anther to the stigma of the flower is called pollination. Pollination can be of two types:
a) Self pollination: transfer of pollen grains occurring in the same flower or between the flowers of the same plant.
b) Cross pollination: transfer of pollen grains between flowers on different plants of the same species.
Pollination mainly occurs by wind, insects, birds and water. In aquatic plants, pollination is done by water.
Insects pollinate flowers when they go in search of food. Flowers produce a sugary liquid called nectar which is consumed by insects. Upon landing on a flower, pollen grains tend to stick to their bodies. When such insects move from one to another flower of the same species, pollen gets transferred to the stigma of flowers thereby causing pollination.
