Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
what causes cells to have a limited life span?
The term Cell can be defined as the structural, functional, and biological units of all living beings. Cells have the ability of replication itself independently so they are also known as the building blocks of life.
Each cell contains fluids known as cytoplasm, Which is covered by a membrane known as cell membrane. Cell organelles such as mitochondrial, Golgi apparatus, endoplasmic reticulum, and nucleus are present in the cytoplasm. Our whole body from head to toe is made up of trillions of cells like we have nerve cells, bone cells, and blood cells, etc.
