What is the Difference Between Embryo Sac and Endosperm?

The main difference between an embryo sac and endosperm lies in their functions and location within the plant.

Embryo Sac:

• Develops within the ovule of flowering plants.
• Contains the egg cells and other structures involved in sexual reproduction.
• Produces an egg cell for the purpose of fertilization.
• Develops before fertilization.

Endosperm:

• Develops within the seeds of flowering plants.
• Provides nutrition in the form of starch, proteins, and lipids to the developing embryo.
• Formed from the primary endosperm nucleus.
• Develops after fertilization.

In summary, the embryo sac is a structure present in the ovule of flowering plants that contains the egg cells and is involved in sexual reproduction. In contrast, the endosperm is a structure present in the seeds of flowering plants that provides nutrition to the developing embryo and develops after fertilization.

Comparative Table: Embryo Sac vs Endosperm

Embryo sac and endosperm are two distinct structures found in the seeds of angiosperms, and they play crucial roles in the plant's reproductive process. Here is a table highlighting the differences between them:

In summary, the embryo sac is a female gametophyte structure that develops within the ovule and produces an egg cell for the purpose of fertilization. In contrast, the endosperm is a nutritive structure that forms after fertilization and provides nutrition to the developing embryo in the form of starch.
