3.24a Mitosis

1. Mitosis is a type of cell division which causes growth which occurs via the increasing numbers of cells. 
2. The number of chromosomes in a nucleus is known as a diploid number (abbreviated as 2n). 
3. The diploid number in a human cell is 46. 2n = 46
4. for cats 2n = 38
5. In the process of mitosis a particular cell divides into two cells, each with a nucleus. When we look inside the nucleus of these cells, we find that each of these cells have a diploid nucleus. 
6. These cells are identical: 
• They have the same number of chromosomes 
• Same set of chromosomes- both cells have identical chromosomes, to each other.
