Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. It occurs concurrently with two types of nuclear division called mitosis and meiosis, which occur in animal cells.
Are cytokinesis and mitosis the same?
Mitosis is the division of the nucleus, while cytokinesis is the division of the cytoplasm. They are both two stages in the cell cycle.
What happens during cytokinesis in meiosis?
A membrane forms around each set of chromosomes to create two new nuclei. The single cell then pinches in the middle to form two separate daughter cells each containing a full set of chromosomes within a nucleus. This process is known as cytokinesis.
What is the relationship between mitosis and cytokinesis?
Mitosis and each of the two meiotic divisions result in two separate nuclei contained within a single cell. Cytokinesis performs an essential process to separate the cell in half and ensure that one nucleus ends up in each daughter cell.
What is the result of mitosis and cytokinesis?
The result of mitosis and cytokinesis is the formation of two identical daughter cells from one cell via cellular division.
Why cytokinesis is not part of mitosis?
No, cytokinesis is separate from mitosis. It is the splitting of the cytoplasm, which occurs after mitosis. Mitosis can occur without cytokinesis, resulting into two nuclei in one cell.
How many times in meiosis does the cytokinesis occur?
In meiosis, cytokinesis must occur twice: once after telophase I and again, after telophase II.
What are the two types of cytokinesis?
The cytokinesis is of two types, one that occurs in the plant cell is cell plate formation and the other in the animal cell is embryonic cleavage.
What are the 10 stages of meiosis?
In this video Paul Andersen explains the major phases of meiosis including: interphase, prophase I, metaphase I, anaphase I, telophase I, cytokinesis, interphase II, metaphase II, anaphase II, and telophase II. He explains how variation is created in the next generation through meiosis and sexual reproduction.
What is the difference between meiosis 1 and meiosis 2?
There are two divisions in meiosis; the first division is meiosis I: the number of cells is doubled but the number of chromosomes is not. This results in 1/2 as many chromosomes per cell. The second division is meiosis II: this division is like mitosis; the number of chromosomes does not get reduced.
