What Is A Normal Type Of Embryo Sac?
An embryo sac is a membrane-bound structure found in female reproductive organs. It is an integral part of the female reproductive system, as it is responsible for the development of the embryo and eventual birth of the baby. The embryo sac is found in most flowering plants and is also referred to as the “integument”.
How Does It Work?
The embryo sac is composed of two layers. The outer layer, or integument, is composed of an outer and inner layer of cells. The inner layer of cells is filled with a jelly-like substance called “endosperm.” This endosperm provides nutrition to the developing embryo, and also serves as a protective barrier. The inner layer of cells helps to protect the embryo from environmental stressors, such as temperature and light.
What Is A Normal Type Of Embryo Sac?
A normal type of embryo sac is typically found in angiosperms, which are flowering plants. This type of embryo sac is known as a “monosporic” embryo sac. It is composed of a single cell layer, with the endosperm being found inside the cell. This type of embryo sac is the most common type found in flowering plants.
What Are The Different Types Of Embryo Sacs?
In addition to the monosporic embryo sac, there are also two other types of embryo sacs. The “bisporic” embryo sac is composed of two cell layers, with the endosperm being found inside the outer layer. The “polysporic” embryo sac is composed of three or more cell layers, with the endosperm being found inside the innermost layer.
Conclusion
A normal type of embryo sac is typically found in angiosperms, or flowering plants. It is composed of a single layer of cells, with the endosperm being found inside. This type of embryo sac is the most common type found in flowering plants. In addition to the monosporic embryo sac, there are also two other types of embryo sacs, the bisporic and polysporic.
