Explain Mitotic Cell Division
Mitotic cell division also known as mitosis is the process of one cell with a nucleus splitting into two cells with a nucleus like the cells in plants animals and fungi. Mitotic cell division stages and significance.

Amoeba is a single celled organism in which the increase in the number of cells or mass is considered to be growth as well as reproduction.
Explain mitotic cell division. It is also called an equational division as the number of parent and progeny cell chromosomes is identical. Mitosis is the phase of the cell cycle where chromosomes in the nucleus are evenly divided between two cells. Kunda and Baum 2009.
It occurs during the M-phase of the cell cycle that completes along with the phase of cytokinesis. The process in cell division by which the nucleus divides typically consisting of four stages prophase metaphase anaphase and telophase and normally resulting in two new nuclei each of which contains a complete copy of the parental chromosomes. In animals division of mitotic cells is only seen in the diploid somatic cells while mitotic divisions in both haploid and diploid cells can be seen in the plants.
Mitotic cell division occurs at different rates in different kinds of cells. After mitosis there is no growth in size rather two new organisms are formed. This is the longest period of the complete cell cycle during which DNA replicates the centrioles divide and proteins are actively produced.
For a complete description of the events during Interphase read about the Cell Cycle. Mitotic cell division produces genetically identical cells from somatic cells while meiosis produces gametes from germ cells that contain different genetic content. The mitotic phase is a relatively short period of the cell cycleIt alternates with the much longer interphase where the cell prepares itself for the process of cell divisionInterphase is divided into three phases.
The mitotic division defines as a kind of eukaryotic cell multiplication that first carry out nuclear division followed by cytoplasmic division and finally forms two identical progenies having the same set of chromosomes as of parent. Mitoses -sez Biology 1. Mitosis or M phase.
When the cell division process is complete two daughter cells with identical genetic material are produced. Hence formation of new cells is considered to be reproduction. G 1 first gap S synthesis and G 2 second gapDuring all three parts of interphase the cell grows by producing proteins and cytoplasmic organelles.
The parent divides into two and forms two new daughter cells. The cell division in which a diploid parent cell divides biologically into 2 diploid daughter cells is called mitotic cell division. However for a complete cell division both mitosis and meiosis should end with cytokinesis.
Mitosis occurs in somatic cells of plants and animals. Because S1 cells form nearly spherical mitotic cells we reasoned that we may be able to alter spindle shape by limiting mitotic cell rounding. In this cell division the two daughter cells have same number of chromosomes as that in the parent cells.
To this end we treated S1 cells with the myosin inhibitor blebbistatin since actomyosin contraction is important for mitotic cell rounding and spindle morphogenesis Kunda et al 2008. Mitosis is a type of cell division in which single haploid cell n or diploid cell 2n divides into two haploid or diploid daughter cells that are same as parent. Mitotic Cell Division Starts with the first division of the fertilized egg mitotic cell division is the process that produces new cells for growth of the new individual and the replacement of worn or damaged cells.
In mitotic cell division the same number diploid number of chromosomes of the parent cell is maintained in each division of the cell.
