Sexual Reproduction in Flowering Plants: The Development of the Ovum (Egg)

The video explains the process of egg development in plants, starting at the base of the carpel in the ovary within structures called ovules. It details the formation of a large diploid cell, the megasporocyte, which undergoes meiosis to produce four haploid megaspores. One megaspore matures into a female gametophyte, forming an embryo sac with eight haploid nuclei. The embryo sac contains an egg cell, synergid cells, antipodal cells, and a central cell with polar nuclei. The polar nuclei fuse with a sperm cell to form the endosperm, which nourishes the developing plant.

Explain the significance of the antipodal cells in the embryo sac.

What is the function of the endosperm in seed development?
