What are the importance of meiotic cell division?

Answer 1

Mitosis is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets in two nuclei.[1] It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two cells containing roughly equal shares of these cellular components. Mitosis and cytokinesis together define the mitotic (M) phase of the cell cycle - the division of the mother cell into two daughter cells, genetically identical to each other and to their parent cell. This accounts for approximately 10% of the cell cycle.

Mitosis occurs exclusively in eukaryotic cells, but occurs in different ways in different species. For example, animals undergo an "open" mitosis, where the nuclear envelope breaks down before the chromosomes separate, while fungi such as Aspergillus nidulans and Saccharomyces cerevisiae (yeast) undergo a "closed" mitosis, where chromosomes divide within an intact cell nucleus.[2] Prokaryotic cells, which lack a nucleus, divide by a process called binary fission.

Answer 2

There are two types of cell division.

Mitosis - The significance of mitosis is that it helps in growth.

The number of daughter cells formed from the parent cell is two.

The chromosome number of the daughter cell is similar to the parent cell.

Meiosis - The significance of meiosis is that it helps in reproduction.

The number of daughter cells formed from the parent cell is four.

The daughter cell has half the chromosome number as that of the parent cell.

Answer 3

Meiotic cell division is a process through which cells are divided. This happens in two stages namely meiosis I and meiosis II and each stage divides the cells once.

Answer 4

Meiosis is the term for a reduction cell division. In this type of division, the number of chromosomes is reduced from a diploid to a haploid number.

Answer 5

Meiosis occurs only with sex cells, and nowhere else in the body.

Answer 6

Meiotic cell division produces four haploid cells.
