Answer 2

Answer:

Pollination is defined as the transfer of pollen grains from another to the stigma of a flower of a plant. There are two types of pollination: i Self Pollination:- It is the transfer of pollen grains from anther to the stigma of the same or genetically similar flower. ii Cross Pollination:- It is the transfer of pollen grain from anther of one flower to the stigma of another flower borne on a different plant of the same species.Two agents of pollination are insects and wind. By the process of pollination pollens grain reaches to the stigma of flower. After that pollen tube develops from pollen grain. Pollen tube develops from pollen grain. Pollen tube contains two male gametes. One male gamete fuses with the egg to form diploid zygote and other male gametes fuses with polar nuclei to form triploid nucleus which develops into endosperm. Thus suitable pollination leads to fertilization.
