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.
Where does cytokinesis occur in meiosis?
The cell plasma membrane pinches, to leave two daughter cells with separate plasma membranes. In meiosis, cytokinesis must occur twice: once after telophase I and again, after telophase II.
Is cytokinesis part of meiosis 1?
Meiosis II is a mitotic division of each of the haploid cells produced in meiosis I. … Cytokinesis follows, dividing the cytoplasm of the two cells. At the conclusion of meiosis, there are four haploid daughter cells that go on to develop into either sperm or egg cells.
Is cytokinesis a phase of mitosis?
Cytokinesis is the final physical cell division that follows telophase, and is therefore sometimes considered a sixth phase of mitosis. All phases of mitosis, as well as the flanking periods of interphase and cytokinesis before and after, are shown in Figure 8.
Does cytokinesis happen after meiosis 1?
Meiosis I ends when the chromosomes of each homologous pair arrive at opposing poles of the cell. … The chromosomes uncoil, forming chromatin again, and cytokinesis occurs, forming two non-identical daughter cells. A resting phase known as interkinesis or interphase II happens in some organisms.
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 is difference between meiosis and mitosis?
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
Is asexual reproduction mitosis or meiosis?
Meiosis does not occur during asexual reproduction. Meiosis is the process of producing gametes (eggs and sperm). Mitosis, on the other hand, is simply the process of cell division.
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.
What are the steps of cytokinesis?
Thus, cytokinesis can be considered to occur in four stages—initiation, contraction, membrane insertion, and completion. The central problem for a cell undergoing cytokinesis is to ensure that it occurs at the right time and in the right place.
