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.

What is Endosperm?

The endosperm is a specialized tissue formed within the seed following fertilization in flowering plants. It typically occupies the space between the embryo and the seed coat, which act as as a nutritive cushion for the developing embryo. It is rich in carbohydrates, proteins, and other nutrients, and acts as a primary source of sustenance for the growing embryo during its initial stages of germination. This nutrient-rich tissue provides the energy and building blocks necessary for the embryo’s development into a fully-fledged plant....

Conclusion – Difference Between Embryo Sac and Endosperm

Embryo sac and endosperm are two distinct structures found in flowering plants (angiosperms) during the process of reproduction. The embryo sac is a female gametophyte structure that develops within the ovule and plays an important role in fertilization and embryogenesis. It contains the egg cell and other supporting cells necessary for reproduction. On the other hand, the endosperm is a nutritive tissue formed after fertilization primarily serving as a source of nourishment for the developing embryo. It is typically triploid (having three sets of chromosomes) and provides essential nutrients such as starch, proteins, and lipids to support the growth and development of the embryo....
