Such purposes include the growth of hair, reproduction of skin cells, fingernails and practically every part of the human body. When a cell goes through the process of reproduction it is known as cell division. The parent cell makes copies of its chromosomes. Then the parent cell splits into two. When the process is finished, the resulting cells called daughter cells become identical to each other and to the parent cell. A set of chromosomes are given to each daughter cell. Imagine a photo copier, making duplicate copies of something. Though there may be slight differences in the overall color and quality, both the original and copies are identical. Millions of cells are constantly reproducing and replacing dead or damaged cells. There are two types of reproduction. We all know that multi cellular organisms
