What is an Embryo Sac?
The embryo sac, also known as the female gametophyte, is present within the ovule of a flowering plant. It is formed through developmental processes within the ovary. Within the embryo sac, various components like egg cells, synergids, antipodal cells, and the central cell with its polar nuclei come together to allow the process of fertilization.
Role in Fertilization
The embryo sac serves as the site where the fusion of male and female gametes occurs, a process vital for the formation of a new plant. Upon pollination, pollen grains deliver sperm cells to the ovule, where they navigate their way to the embryo sac. Here, fertilization takes place, leading to the formation of a zygote, the initial stage of embryo development.
Significance in Plant Life Cycle
The embryo sac marks an important stage in the life cycle of flowering plants, bridging the gap between pollination and the process of embryo development. It serves as a site for the union of gametes, ensuring the continuity of plant species through the generation of new individuals.
Difference Between Embryo Sac and Endosperm
The difference between embryo sac and endosperm lies in the fact that the embryo sac is a structure within the ovule where the female gametophyte develops, while the endosperm is a nutritive tissue formed during seed development that provides nourishment to the developing embryo.
The embryo sac and endosperm are the two most important structures present in flowering plants. While the embryo sac contributes to forming the new plant, the endosperm nourishes it during its early growth stages. In this article, we will study the difference between embryo sac and endosperm and some similarities between them.
