WHAT IS OOGENESIS ? WHAT IS THE ROLE OF POLAR BODY ? |
| Oogenesis is the production of an ovum or egg cell, the female gamete or sex cell. It is one type of gametogenesis, or sex cell production. Oogenesis happens in all sexually reproductive species, and it includes all of the immature stages of the ovum. A polar body, sometimes referred to as a polar cell, is a cell found within the ovum of mammals as well as plants. It is the byproduct of the natural process of cell division during oogenesis and meiosis.In mammals, the polar body is not a functional reproductive cell, and it disintegrates after a period of time. |
