Each dividing cell is called mother cell, and its descen dants are called daughter cells, which are to become mother cells in their cell division actually, passing along the same genes they inherited from their mother to yet another new cellular generation. Therefore, cell division is often referred to as cell reproduction. Cell reproduction is a process of cell proliferation by which cell numbers or cell population become often larger continually. Cell reproduction have mainly three types: amitosis, mitosis and meiosis. Cell proliferation may be controlled normal cell reproduction but may become malignant cell proliferation losing normal controlling. Cell growth includes two meaning, one is that cell size become larger during development, another is the increase of cell numbers by cell proliferation. In most cases the meaning of cell growth is equal to cell proliferationEach dividing cell is called mother cell, and its descen- dants are called daughter cells, which are to become mother cells in their cell division actually, passing along the same genes they inherited from their mother to yet another new cellular generation.
