Cell division is a biological process by which a cell divides into two or more cells. During cell division, the cell nucleus splits and the DNA is replicated. There are two types of cell division - mitosis and meiosis. In mitosis, parent cell divides into daughter cells, each with a complete copy of the genetic material of the parent and with the capability to divide again. In meiosis, after division, cells have half the genetic material of the parent, and have to undergo fertilization to form a zygote, which is capable of further division.
