![]() Mitosis produces new cells, and replaces cells that are old, lost or damaged. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis is a way of making more cells that are genetically the same as the parent cell. This cell then divided and divided to make more cells through a process called mitosis. But you started life as a single cell - a fertilised egg cell. ![]() Your body contains trillions of cells (thousands of millions). The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set. Mitosis is used to produce daughter cells that are genetically identical to the parent cells. Mitosis and meiosisĬells divide into two different ways to make new cells. Cells that are not dividing leave the cell cycle and stay in G0. The period between cell divisions is known as 'interphase'. The cell separates the copied chromosomes to form two full sets (mitosis) and the cell divides into two new cells (cytokinesis). The cell checks the duplicated chromosomes and gets ready to divide. Each chromosome now consists of two sister chromatids. The cell makes copies of its chromosomes. The cells grow, copy their chromosomes, and then divide to form new cells. On the other hand, in meiosis, the division of germ cell involves two fission of the nucleus and produce four gametes, sex cells.Living cells go through a series of stages known as the cell cycle. In the mitosis cell division process, the cell divides in the two genetically identical daughter cells. Mitosis and Meiosis are the two ways of cell division and reproduction. It takes part in the formation of gametes and maintenance of the chromosome. It takes part in healing and repair of body cells. The DNA replicates once for two cell division. The DNA replicates once for one cell division and the DNA replication takes place during Interphase 1. For example: Male sperm cells and female egg cells. The number of chromosomes reduced by half. The number of chromosomes remain the same. There are two cell divisions occur in meiosis: first and second meiotic divisions. Yes, chromosomes are mixed and crossing over occurs. For example: animls, humans, plants, fungi etc. It occurs only in sexually reproducing organisms. It occurs in both sexually as well as asexually reproducing organisms. It is responsible for genetic diversity through sexual reproduction. ![]() It is responsible for cellular reproduction, general growth and the repair of the body. It takes place in somatic cells of the body. In this type of cellular reproduction, the number of chromosomes are reduced by half. Meiosis is a modified type of cellular division in sexually reproducing organisms.It takes two rounds of cell division but only one round of DNA replication. Mitosis is a process of nuclear division in eucaryotic cells.In this process of reproduction, the cell division produces a replica, with the same number of chromosomes in each resulting cell. A list of differences between Mitosis and Meiosis are given below: No. ![]() Mitosis vs Meiosis: There are many differences between Mitosis vs Meiosis.
