What is cell division used for?

Answer 1

1. Growth - by increasing the number of cells in tissues

2. Embryonic development - by producing more specialized cells to form many tissues, organs etc

3. Tissue repair - by replacing dead / injured cell

4. Asexual reproduction - direct replication of DNA, creating two identical daughter cells (usually for unicellular organisms such as bacteria to maintain a population)

Answer 2

Mitosis is the process of reproduction used by simple organisms. Through this process, the cell completes 4 stages: # Prophase # Metaphase # Anaphase # Telophase. In prophase, the cell's DNA-protein fibers condense to become chromosomes and the nuclear membrane and nucleolus disassemble. Next comes metaphase, in which the chromosomes line up in the cell. Then anaphase, where the chromosomes separate and move apart. And finally telophase, where the chromosomes uncoil and the nuclear membrane and nucleolus reforms. At this point, ther are two new cells. Mitosis is different from meiosis in that it is nonsexual reproduction, and is only used by very simple organisms.

Answer 3

Cell division is used for repair and replenishment of cells as well as growth (mitosis). Meiosis, another form of cell division, is used for production of haploid gametes (sex cells such as sperm and eggs).

Answer 4

Mitosis is a form of division in which a single cell splits into two identical daughter cells. This is used as a form of replication - and is mostly used to replace dying cells. It is also involved in asexual reproduction - which some organisms undergo.

Answer 5

Mitosis is used by the somatic cells to divide the nucleus with equal number of chromosomes. It is used after interphase (more specifically G2 phase).
