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.
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.
