Question

How would u explain the concept of cell division to a non-science student

Answer 1

Answer:

Cell division is the process by which a parent cell divides into two or more daughter cells.[1] Cell division usually occurs as part of a larger cell cycle. In eukaryotes, there are two distinct types of cell division: a vegetative division, whereby each daughter cell is genetically identical to the parent cell (mitosis), and a reproductive cell division, whereby the number of chromosomes in the daughter cells is reduced by half to produce haploid gametes (meiosis).[2] Meiosis results in four haploid daughter cells by undergoing one round of DNA replication followed by two divisions. Homologous chromosomes are separated in the first division, and sister chromatids are separated in the second division. Both of these cell division cycles are used in the process of sexual reproduction at some point in their life cycle. Both are believed to be present in the last eukaryotic common ancestor.

Prokaryotes (bacteria) undergo a vegetative cell division known as binary fission, where their genetic material is segregated equally into two daughter cells. While binary fission may be the means of division by most prokaryotes, there are alternative manners of division, such as budding, that have been observed. All cell divisions, regardless of organism, are preceded by a single round of DNA replication.

For simple unicellular microorganisms such as the amoeba, one cell division is equivalent to reproduction – an entire new organism is created. On a larger scale, mitotic cell division can create progeny from multicellular organisms, such as plants that grow from cuttings. Mitotic cell division enables sexually reproducing organisms to develop from the one-celled zygote, which itself was produced by meiotic cell division from gametes.[3][4] After growth, cell division by mitosis allows for continual construction and repair of the organism.[5] The human body experiences about 10 quadrillion cell divisions in a lifetime.[6]

The primary concern of cell division is the maintenance of the original cell's genome. Before division can occur, the genomic information that is stored in chromosomes must be replicated, and the duplicated genome must be separated cleanly between cells.[7] A great deal of cellular infrastructure is involved in keeping genomic information consistent between generations.

Answer 2

The concept of Cell Division

Explanation:

Significance of Cell Division:

• Cell division is the method in which parent cell is split into offspring cells.
• It generates progeny.
• It includes fixing of cells

Types of Cell division:

• There are two kinds of cell division particularly mitosis and meiosis.
• Mitosis effects in the generation of daughter cells which includes the same quantity of the chromosomes as in their parent cell.
• It takes place essentially in somatic cells (Body cells) of the bions.
• It plays a significant role in the fullness of a bion.
• It helps in the replacement of damaged cells.
• It is the main part of asexual reproduction.
• Meiosis the reduction state in which four daughter cells are generated.
• In this state, the number of chromosomes is decreased from 2n to n.
