Cell Division vs Mitosis
Self-replicating ability is considered as one of the great characteristic feature of most living organisms as it helps for their growth and reproduction. Self-replication is an organized and continuous process, hence called cell cycle. Cell cycle is composed of four basic phases including cell division, G1, S, and G2 phases. Mitosis comes under the cell division. In addition, cytokinesis is also considered as a part of cell division.
Cell division is the process of self-replication and resulting new daughter cells. It includes two processes; nuclear division and cytokinesis. Nuclear division can be divided into two processes, namely mitosis and meiosis. Mitotic cell division produces genetically identical cell from somatic cells while meiosis produces gametes from germ cells that contain different genetic content. However, for a complete cell division, both mitosis and meiosis should be ended up with cytokinesis. This is also an important process, and in both cases, considered as a part of cell division. Cytokinesis is the actual division of cytoplasm followed by nuclear division. In animal cells, it occurs by means of constriction of the plasma membrane at the cell equator while, in plant cells, it occurs by forming a plate at the cell equator.
The production of two genetically identical daughter nuclei from a parent nucleus is known as mitosis. It only occurs in somatic cells and helps the growth of organisms. Mitosis includes following four phases; prophase, metaphase, anaphase, and telophase. Before mitosis occurring, DNA replication must be occurred in order to double the number of chromosomes. During prophase, the nuclear membrane and nucleolus disappears, while chromosomes condense and become visible. In metaphase, chromosomes arrange themselves at the cell equator as the spindle formation is completed. The sister chromatids start to separate during the anaphase. Finally, when chromosomes reach the poles of cell, nuclear membrane reformed to surround each set of chromosomes.
What is the difference between Cell Division and Mitosis?
• Cell division is the process of self-replication of cells, whereas mitosis is the division of cell nucleus resulting two genetically identical daughter cells.
• Cell division includes nuclear division and cytokinesis, whereas mitosis consists of four phases; prophase, metaphase, anaphase, and telophase.
• Both somatic and germ cells undergo cell division, whereas only somatic cells undergo mitosis.
• Cell division takes more time to complete than the completion of mitosis.
