The Process of Pollination and Fertilization in Angiosperms

Biology

This text explains the process of pollination, where a pollen grain lands on the stigma, germinates, and forms a pollen tube. It details the journey of the male gametes within the pollen tube to the ovule and embryo sac, where fertilization occurs by fusing with the ovum and polar nuclei.
