What is the name of the process when the pollen meets the ovum?

The process when pollen meets the ovum is called fertilization. During this process, pollen grains transfer from the male part of a flower (anther) to the female part (stigma), and the sperm cells within the pollen then unite with the ovum, leading to the formation of a zygote. This is a crucial step in plant reproduction, ultimately resulting in seed development.
