Reproduction in flowering plants involves the production of male and female gametes, the transfer of male gametes to female eggs in a process called pollination. After pollination fertilization occurs and the eggs grow in seeds inside a fruit. The genesis of the plant embryo is the process that produces an embryo from the plant of an egg fertilized by asymmetric cell division and differentiation of undifferentiated cells into tissues and organs.
