Concepts Used:

Pollination and Double Fertilization

Pollination is defined as the pre-fertilization event or process, where pollen grains from another are transferred to the stigma of a flower.

Double fertilization is a complex process that involves the fusion of one female gametophyte with two male gametes.

Types of Pollination:

All plants having flowers completely rely on the pollination method for reproduction. There are 2 types of pollination –

  • Self Pollination
  • Cross-Pollination

The end products of double fertilization are:

  • Diploid Zygote
  • Primary Endosperm Nucleus
