MITOSIS : is called equational division because number of chromosomes remain equal before and after division. or in other way, if parent cells is haploid then the resultant daughter cells will also be haploid. But if parent cell is diploid then the resultant daughter cells will also be diploid.
Moreover, is mitosis equational division?
Mitosis is the process of cell division wherein the chromosomes replicate and get equally distributed into two daughter cells. The chromosome number in each daughter cell is equal to that in the parent cell, i.e., diploid. Hence, mitosis is known as equational division.
Secondly, is mitosis also called reduction division? Meiosis is called reduction division because number of chromosomes in daughter cells is reduced to half than that of parent cell. Mitosis and meiosis provides cellular division, but not only the cells divide, but they get bigger.
Simply so, which cell division is called Reductional division and why?
Meiosis
What is Reductional division in meiosis?
Medical Definition of Reduction division Reduction division: The first cell division in meiosis, the process by which germ cells are formed. In reduction division, the chromosome number is reduced from diploid (46 chromosomes) to haploid (23 chromosomes). Also known as first meiotic division and first meiosis.

Why is it called equational division?
The chromosome number in each daughter cell is equal to that in the parent cell, i.e., diploid. Hence, mitosis is known as equational division. Answer: Mitosis is called equational division because the number of chromosomes after undergoing mitosis remains the same.
What is equational division in biology?
MITOSIS : is called equational division because number of chromosomes remain equal before and after division. Meiosis 1 : its reductional division as number of chromosomes are reduced to half ( i.e. number of chromosomes in parent cell is twice the number of chromosomes in daughter cells).
Where does mitosis occur in the body?
Mitosis occurs in every cell of the body except in germ cells which are produced from meiotic cell division.
What is g0 of cell cycle?
The G0 phase (referred to the G zero phase) or resting phase is a period in the cell cycle in which cells exist in a quiescent state. G0 phase is viewed as either an extended G1 phase, where the cell is neither dividing nor preparing to divide, or a distinct quiescent stage that occurs outside of the cell cycle.
What is equatorial division?
equatorial division The division of each chromosome during the metaphase of mitosis or meiosis into two equal longitudinal halves which are then incorporated into separate daughter nuclei. A Dictionary of Plant Sciences. × “equatorial division .”
What is Karyokinesis in biology?
Medical Definition of Karyokinesis Karyokinesis: During cell division, the process of partition of a cell’s nucleus into the daughter cells. See also: Cytokinesis; Mitosis.
Can there be DNA replication without cell division?
There can be DNA replication without cell division. During cell division, the parent cell gets divided into two daughter cells. However, if there is a repeated replication of DNA without any cell division, then this DNA will keep accumulating inside the cell.
Can there be mitosis without DNA replication?
Mitotic cell division cannot take place without DNA replication in S phase. DNA duplication is important as it maintains the chromosome number in the daughter cells and hence mitosis is an equational division. Therefore, the duplication of DNA is an essential step and without it, no mitosis can take place.
What is the end product of meiosis 1?
However, Meiosis I begins with one diploid parent cell and ends with two haploid daughter cells, halving the number of chromosomes in each cell. Meiosis II starts with two haploid parent cells and ends with four haploid daughter cells, maintaining the number of chromosomes in each cell.
What is the end product of mitosis?
Mitosis ends with 2 identical cells, each with 2N chromosomes and 2X DNA content. All eukaryotic cells replicate via mitosis, except germline cells that undergo meiosis (see below) to produce gametes (eggs and sperm).
How many cells are produced in meiosis?
four
What is the end product of meiosis 2?
5.5 The Two Parts of Meiosis-Meiosis II In contrast to a mitotic division, which yields two identical diploid daughter cells, the end result of meiosis is haploid daughter cells with chromosomal combinations different from those originally present in the parent. In sperm cells, four haploid gametes are produced.
What is importance of meiosis?
Significance. Meiosis is responsible for the formation of sex cells or gametes that are responsible for sexual reproduction. It activates the genetic information for the development of sex cells and deactivates the sporophytic information. It maintains the constant number of chromosomes by halving the same.
What is the purpose of meiosis?
Meiosis, on the other hand, is used for just one purpose in the human body: the production of gametes—sex cells, or sperm and eggs. Its goal is to make daughter cells with exactly half as many chromosomes as the starting cell.
