Question

Meiosis is also known as
A. Mitosis
B. Multiplication division
C. Reductional division
D. Both A and C

Answer 1

Hint: Cell division is a process by which the parent cell divides into two or more daughter cells. Cell division usually occurs as a part of a larger one. two kinds of cell division are present: one is mitosis and other is meiosis. Mitosis causes the formation of somatic cells and meiosis causes the formation of gametes.

Complete answer:
Meiosis is an exceptional kind of cell division known as reductional division The cellular division in meiosis I am called the reductional division because it causes reduction of the chromatids number from diploid (the cell has two copies of each chromosome, one maternal and one paternal chromosome) to haploid (the cell has only one copy of each chromosome, either maternally-derived or paternally. Meiosis, DNA replication is followed by two rounds of cell division to produce four daughter cells, i.e. meiosis I and meiosis II,

Meiosis I-
1. Interphase: The DNA within the cell is traced leading to 2 identical full sets of chromosomes. Outside of the nucleus, are 2 centrosomes, each containing a try of centrioles, these structures are important for the method of cellular division During interphase, microtubules extend from these centrosomes.
2. Prophase I: chromosomes condense into X-shaped structures that may be simply seen below a magnifier. Each chromosome consists of 2 sister chromatids. Chromosomes could then exchange bits of DNA in an exceeding method referred to as recombination or crossing over. At Final of Prophase I, the membrane around the nucleus within the cell dissolves away, releasing the chromosomes.
3. Metaphase I: The chromosome pair to every alternative along the centre (equator) of the cell. The centrioles are currently at opposite poles. The cell division spindle fibres attach to at least one chromosome of every pair.
4. anaphase I: The pair of chromosomes are then forced apart by the cell division spindle, that pulls one chromosome to one pole of the cell and therefore the other chromosome to the other pole.
5. Telophase I and cytokinesis: The chromosomes complete their move to the other poles of the cell. At each pole of the cell, a full set of chromosomes gather along. A membrane forms and then cytokinesis follows.

Meiosis II-
6. Prophase II: Now there are 2 daughter cells, every with twenty-three chromosomes (23 pairs of chromatids. The membrane around the nucleus in every cell dissolves away releasing the chromosomes. The centrioles duplicate. The cell division spindle forms once more.
7. Metaphase II: In every of the 2 female offspring cells the chromosomes (pair of sister chromatids) line up end-to-end on the equator of the cell.
8. phase of cell division II: The sister chromatids are then pulled to opposite poles because of the action of the cell division spindle.
9. Telophase II and cytokinesis: The chromosomes complete their move to the other poles of the cell. At every pole of the cell, a full set of chromosomes gather along. A membrane forms around every set of chromosomes to make 2 new cell nuclei. This is the last section of meiosis, but the cellular division isn't complete while not another spherical of cytokinesis. Once cytokinesis is complete there are four granddaughter cells, every with half a group of chromosomes (haploid), causing a reductional division.

A correct answer is an option (C).

Note:
Meiosis occurs in all sexually reproducing single-celled and multicellular organisms (which are all eukaryotes), including animals, plants and fungi It is an essential process for oogenesis and spermatogenesis. By the means of reductional division. It includes two rounds of division at the last outcome in four cells with just one duplicate of each fatherly and maternal chromosome (haploid).
