Question 1
Mitosis and meiosis are the essential processes that enhance growth of both plants and animals. The two processes serve various purposes as outline in this essay. Mitosis enhances multiplication of cells, in multcellular organism, from a single cell fused from egg and a sperm to numerous cells. Mitosis is also important in the growth of single-cell organisms, but in this case, the process helps in production since making of a new cell in a single-cell organisms mean new organism. On the other hand, serves a primary function of creating reproduction cells in the ovaries and testes.
The different between miotosis and meiosis is the fact that meiosis generates cells that comprise half the chromosomes involves mitosis. Therefore, during fertilization of cells of organism, the cell contains right number of chromosomes, half generated from the mother and the other half by the father.
Question 2
The cell cycle is reffered to as the arranged or ordered sets of events, terminating in the growth in a normal cell and splitting into two daughter cells. In a normal cell, cell cycle is essential in the regulation of growth in a cell. However, when regulation of a cell growth is lost, the normal cells develop to cancerous cells. Cancerous cells therefore, have mutations in the genes, known as proto-oncogenes, which regulate the cell cycle. They contain tumor suppressor genes that hinders the division of a cell to multiples cell is needed. Thus, the cancerous cells are in condition where the behavior and growth of a normal cell is lost.
Question 3
Meiosis involves a process in a cellular production where number of chromosomes is divided into two halves through the division of homologous chromosomes in a diploid cell. On the other hand, mitosis is a sexual production process where cell splits into two to generate a replica, with an equal amount of chromosomes in haploid cell. The two processes are in form of cell division and encounters alike cell cycles.
The replication of DNA is involved into two the processes where the breakdown of nuclear membrane occurs prior to the new cell creation. The function of meisosis is sexual production while that of mitosis is cellular reproduction, repair and growth of the body of an organism. In the cross over, meiosis encounters mixing of chromosomes while crossing over is not experienced in mitosis. Mitosis occurs in all organisms while meiosis occurs strictly on animals, human, plants and fungi.
Question 4
The main advantage of sexual reproduction is that it generates the diversity of genetic within the species or population. This is facilitated by the creation of unique and new amalgamation of genes by combining the genes for each traits provided by the two parents. The variation is enhanced in the random assortment of homologous diploids and crossing over during meiosis. The incredible depot of genetic variation offers adaptation to the evolving environment. By doing this, the meiosis assist in ensuring that the sexual organism does not go extinct.
In conclusion, the sexual production through meiosis promotes the characters diversity in the species by offering genetic variation. Therefore, this process plays and essential role in the reproduction of new offspring that have different characteristics. This results into constant evolution of different species to develop better organisms. Not all this advantages are offered by the asexual production.
