What is a simple definition of cytokinesis?
cytokinesis, in biology, the process by which one cell physically divides into two cells. Cytokinesis represents the major reproductive procedure of unicellular organisms, and it occurs in the process of embryonic development and tissue growth and repair of higher plants and animals.
What is cytokinesis short answer?
Cytokinesis (/ˌsaɪtoʊkɪˈniːsɪs/) is the part of the cell division process during which the cytoplasm of a single eukaryotic cell divides into two daughter cells. Cytoplasmic division begins during or after the late stages of nuclear division in mitosis and meiosis. It divides the cell into two daughter cells.
What is cytokinesis kid definition?
Cytokinesis is the division of cells after either mitosis or meiosis I and II. During cytokinesis, the cytoplasm (the liquid center of the cell that holds the organelles into place) splits into two equal halves, and the cell becomes two daughter cells.
What is the best description for cytokinesis?
Cytokinesis: 1. During cell division, the process that partitions the cellular contents including the chromosomes, cytoplasm, and organelles into the two daughter cells. Cytokinesis occurs just after the segregation of the duplicated genome.
What is cytokinesis biology discussion?
Cleavage cytokinesis. It occurs in animal cells and pollen mother cells of some angiosperms. In this process, a cleavage furrow appears at the middle, which gradually deepens and breaks the parent cell into two daughter cells. A special structure called mid body is formed in the centre, and it is a centripetal process.
What is cytokinesis example?
For example, spermatogenesis, a meiosis cell division process is symmetrical cytokinesis where the newly formed sperm cells are equal in size and content, while biogenesis is a typical example of asymmetrical cytokinesis, producing a large cell and 3 polar bodies.
What is cytokinesis quizlet?
Cytokinesis. the physical process of cell division which divides the cytoplasm of the cell into two daughter cells. It occurs with two types of nuclear division. mitosis and meiosis.
What is the goal of cytokinesis?
In general, the goal of cytokinesis is common in all organisms: to physically separate a mother cell into two daughter cells.
What are the characteristics of cytokinesis?
Cytokinesis is the process in which the cell actually divides into two. With the two nuclei already at opposite poles of the cell, the cell cytoplasm separates, and the cell pinches in the middle, ultimately leading to cleavage.
What is cytokinesis How does it occur?
Cytokinesis is the process whereby the cytoplasm of a parent cell is divided between two daughter cells produced either via mitosis or meiosis. Cytokinesis begins in anaphase in animal cells and prophase in plant cells, and terminates in telophase in both, to form the two daughter cells produced by mitosis.
Why is cytokinesis important during the embryonic development?
Cell division is a key process shaping normal embryonic development. Mitosis involves the segregation of the replicated genome (karyokinesis) and separation of the cytoplasmic content (cytokinesis). Understanding cell division is thus crucial to understand developmental processes, leading to tissue and organ formation.
How does cytokinesis differ in plants and animals?
Cytokinesis occurs in mitosis and meiosis for both plant and animal cells. The ultimate objective is to divide the parent cell into daughter cells. In plants , this occurs when a cell wall forms in between the daughter cells. In animals , this occurs when a cleavage furrow forms.
Why is cytokinesis so important?
Cytokinesis is part of the cell cycle, it is the last stage where a plate forms between both the cells to separate them from each other and to form two individual cells. Mitosis is important because it is a fast way of producing replicas of cells. Cytokinesis is important to differentiate or create boundaries between the cells.
How do you use cytokinesis in a sentence?
The developing male germ cells do not complete cytokinesis during spermatogenesis.
What is another word for cytokinesis?

What happens to chromosomes during cytokinesis?
The movements of cytokinesis seen in the cell are caused by the same spindle network that was responsible for the separation of the chromosomes. Parts of the spindle responsible for moving chromosomes break down in late cell division, to be used in restructuring the two new cells.
