Fertilization in Plants


Fertilization 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 a 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.
- Distinguish between male and female gametes.
- Explain the role of two sperm cells in the process of fertilization in plants.
- Identify and arrange the various events that occur during double fertilization in plants.
- Name the end products of double fertilization in plants.
