Pollination |
Fertilization |
Pollination is the transfer of pollen grains carrying male gametes from the anther to pistil of a flower. Pollination is of two types—self pollination and cross pollination. |
Fertilization is the fusion of male and female gamete to form a zygote. It is also of two types—internal fertilization and external fertilization. |
Pollination occurs with the help of certain agents such as wind, water or animals |
Fertilization occurs after pollination when the pollen grain resides on stigma and forms a pollen tube to transfer the male gamete into the embryo sac in the ovary. |
