Fertilization in Plants

Description

Overview

Fertilisation in plants begins after the transfer of pollen grains to the stigma of the gynoecium. This is followed by the germination of pollen grain and formation of pollen tube. The pollen tube, carrying the two male gametes, enters the female gametophyte present in the ovule inside the ovary. Inside the female gametophyte, two fusion processes occur and complete the process of fertilization.

Learning objectives

After completing this module, you will be able to:
- Trace the path of pollen tube from its formation on the stigma to its entry inside the female gametophyte.
- Identify the location and name of the male and female gametes.
- Explain the role of two sperm cells in the fertilisation in plants.
- Organize the events that lead to double fertilisation in plants.
