Cell Division

Cell division, is the splitting up of a cell into two or more cells during the process of growth or reproduction.As a result, the  cell nucleus splits and DNA is reproduced. It helps in reproduction of single celled organisms and growth in multicellular organisms (Alberts, n.p). The two types of cell division are meiosis and mitosis.

How Divison of Cells happens

Mitosis usually occurs when the parent cell splits into two identical daughter cellsand resembles the original parent cell with the capability to divide again. Mitosis involves several stages namely, “Interphase, Prophase, Metaphase, Anaphase, Telophase and Cytokinesis.”

Through meiosis, cells split into sperms and eggs. Here, one parent produces four daughter cells, having “half number of the number of chromosomes found in the original parent cell.” Its DNA replicates once while its nucleus splits twice. Meiosis has two key stages; meiosis I and meiosis II with both futher breaking down into four substages.

In mitosis, cells  replicate their  contents before splitting to form two identical daughter cells.It can lead to health complications such as cancer if not well checked. On the other hand, meiosis greatly enhances genetic variation and ensures continuity of the  same number of chromosomes in humans by reducing the chromosome number by half during the production of eggs and sperms. In summary, mitosis is an asexual process, its cells divide only once and the results are two daughters cells with identical  genetic information.Meiosis on the contrary is sexual; its cells divide twice forming  four haploid daughter cells with different genetic information.Both of these processes determine the genetic make up of organisms as well as their characteristics as they mature.
