Question

an essay on pollination from the book flowers are calling​

Answer 1

Answer:

pollination:

generally pollen grains have a tough protective coat which prevents them from drying up.since pollen grains are light,they can be carried by wind or water.insects visit flowers and carry away pollen on their bodies.some of the pollen lands on the stigma of a flower of the same kind.the transfer of pollen from the anther to the stigma of a flower is called pollination.if the pollen lands on the stigma of the same flower or another flower of the same plant,it is called self pollination.when the pollen of a flower lands on the stigma of a flower of a different plant of the same kind,it is called cross-pollination.

Answer 2

Details on pollination is given below :

It is the phenomenon where the male gamete from the anther falls or gets transferred on the stigma of the carpel of the female flower. The pollen grains may get transferred by insects like bees, wind, birds, etc.

When the male gamete falls or lands on the stigma, it gets germinated when they get suitable or favorable conditions. Then, pollen tube formation occurs through which the male gamete enters the embryo sac and gets fused with the egg resulting in the formation of zygote.
