explain the process of mitosis
Answers
Answer:
Explanation:
Cell division is the driving process of reproduction at the cellular level. Most eukaryotic cells divide in a manner where the ploidy or the number of chromosomes remains the same, except in the case of germ cells where the number of chromosomes is halved.
Mitosis
Mitosis Diagram showing the different stages of mitosis
Mitosis is the phase of the cell cycle where the nucleus of a cell is divided into two nuclei with an equal amount of genetic material in both the daughter nuclei. It succeeds the G2 phase and is succeeded by cytoplasmic division after the separation of the nucleus.
Mitosis is essential for the growth of the cells and the replacement of worn-out cells. Abnormalities during mitosis may alter the DNA, resulting in genetic disorders.
Features of Mitosis
In each cycle of cell division, two daughter cells are formed from the parent cell.
The cell is also known as equational cell division because the chromosome number in the parent cell and daughter cell is the same.
In plants, mitosis leads to the growth of vegetative parts of the plant like root tip, stem tip, etc.
Segregation and combination do not occur in this process.
The processes occurring during mitosis have been divided into different stages.
Stages of Mitosis
Right before prophase, the cell spends most of its life in the interphase, where preparations are made before the beginning of mitosis (the DNA is copied). However, since the actual process involves the division of the nucleus, prophase is technically the first stage of this process.
