What is cytokinesis? – How is this process carried out in cells?
Biology is the science that studies these processes and other aspects of living beings in their structure, function, evolution and distribution. Cytokinesis is a critical process that takes place in eukaryotic cells. towards the end of the cell cycle which causes the division of the cytoplasm and the separation of two daughter cells.
The process begins with the formation of a contractile ring, consisting of actin filaments and myosin motors, which constrict and divide the gamete into two parts. Then in this article you will know all the evolution of cytokinesis in cells. Since it is a crucial transformation in cell division that allows the formation of new cells and tissues.
Concept and meaning of cytokinesis
is the procedure end Of Cell Division, in which the cytoplasm divides into two daughter cells. This development is essential for cell reproduction and the formation of new tissues in multicellular organisms.
During cell division, two complementary processes take place: karyokinesis, which is the division of the nucleus into two daughter nuclei, and cytokinesis, which is the division of the cytoplasm into two separate daughter cells.
During mitosis, the gamete divides into two parts: the first is the deviation of the chromosomes towards the opposite poles of the cell, while the second is the separation of the cytoplasm. The procedure he performs also involves fixing the genetic material, before the final fraction occurs.
The success of this is essential to have effective cell reproduction. Cytokinesis begins in anaphase, when microtubules form a contractile ring around the center of the cell. This connection contracts, dividing the cytoplasm into two parts and makes a fissure called the dividing furrow.
In animal organisms, cytokinesis is complete when the actin-myosin ring contracts enough to divide the cell into two daughters. In plant organisms, instead of a ring of actin and myosin, a cell plate is made that is split in two to generate them.
Similarly, a plant cell divides into two. Within this link, a structure called a bifurcation is made. This contains the microtubules and actin filaments. Necessary for create the cell membrane. This contracts as the microtubules and actin filaments build the new membrane between the two daughter cells. After cell division is complete, both will have the same amount of genetic material as before.
What is cytokinesis in the animal cell?
In animal cells, this process involves the use of a contractile ring composed of actin and myosin fibers, which surrounds the equator of dividing cells. As the strands contract, the ring narrows, producing an incision in the cell surface.
This puncture completely divides the two daughter cells into equal parts. This is necessary, so that each cell receives its required genetic material. Know the function of cytokinesis in cells, can give us important information, on which to regenerate and repair. Likewise, due to the ability to renew your damaged or lost cell tissues.
What is cytokinesis in the plant cell?
In the particular case of plant cells, this process involves the formation of a dividing cell wall called the cell plate. It develops along the equatorial plane and acts as a barrier between daughter cells. This process is crucial to keep plant tissue healthy and functional, as it guarantees the correct distribution of cell organelles and allows uniform growth.
In plant cells, is regulated by molecular interaction and depends on internal factors. This refers to the activation of the cytoskeleton. Even from external elements, such as the adequate availability of nutrients and water in the cellular environment.
In plant cells, cytokinesis involves the formation of a phragmoplast. This is a structure of microtubules and vesicles that assemble at the equatorial plane of the cell to divide the cytoplasm. Furthermore, cytokinesis also plays an important role in plant reproduction. During gamete formation, it allows for the separation of the male and female sex cells, which is essential for successful fertilization.
That is why cytokinesis is also crucial in the formation of meristems, the plant tissue responsible for plant growth and regeneration. In short, cytokinesis is a fundamental process in plant cells which guarantees the correct distribution of cell organelles and uniform growth.
What is cytokinesis?
It is the final development of cell division that involves partitioning of the cytoplasm and cellular material, separate daughter cells are generated. It is essential to maintain a proper balance in healthy tissues, it also contributes to embryonic development and tissue regeneration.
Understanding how it works may have implications in the treatment of diseases such as cancer. Due to cell proliferation out of control. Cytokinesis is the process of cell division that occurs at the end of mitosis and meiosisin which the two nuclei are separated in treated daughter cells.
In this phase, a contractile structure called the contractile ring forms around the center of the cell, located in the equatorial plane. This link is It is made up of actin and myosin filaments. They begin to contract, dividing the mother cell; after separating the chromosomes.
When the ring reaches its maximum size, an internal groove is produced which divides the daughter cells completely. This is how two new independent cells are created with their own cell wall.
When does cytokinesis occur?
It occurs in the last stage of the cycle and is essential for proper cell maintenance. It is a crucial procedure in the life of cells, since it allows the formation of new daughter cells with the genetic information necessary for its proper functioning. In addition, this process is relevant for the repair of damaged tissues, the growth and development of organisms.
What is the importance of cytokinesis?
It is crucial in cell division, because it ensures that the genetic material is distributed equally among the daughter cells. During mitosis, the cell divides into two parts using a contractile ring of protein that forms around the cell.
As mentioned, this ring initially allows the mother cell to divide into two separate and identical daughter cells. each with its own complete set of chromosomes and an equivalent amount of cytoplasm and cell organelles. Without proper cytokinesis, genetic errors can occur. Having abnormal cell formation, with incomplete or excessive sets of chromosomes.
In short, the importance of this lies in ensuring that each new cell, has a complete set of dna, since it is necessary to survive and fulfill its functions within the organism.
What is the end result of cytokinesis?
The effect of all this evolution is the physical separation of the two daughter cells, each of which contains genetic material identical to that of its parent cell. This process involves a contractile ring composed of actin and myosin filaments that surround the cell.
The ring contracts pulling on the plasma membrane inward and forming a cleavage furrow until it reaches the midline of the cell. Once this occurs, a new plasma membrane is generated to separate the two newly formed cells.
Through this procedure, organelles and cytoplasmic components, are distributed between both daughter cells. Thanks to cytokinesis, organisms can grow and develop continuously. As well as regenerate damaged tissues in cell division.
Therefore, we can conclude that cytokinesis It is a necessary step for the development and growth of organisms. Current information on the subject suggests that cytokinesis must be regulated by mechanisms that involve biochemical processes. It has been shown that certain proteins and microRNAs have a crucial role in the control of the actin-myosin contractile ring, which plays a decisive role in the completion of the cytokinesis process.
These processes are essential for cell reproduction and for the formation of new organisms, as occurs during pregnancy. While there are still unknown aspects of how this progress occurs at the molecular level, more and more research and studies carried out on this subject. It is important to take all this into account for your understanding, because it will influence future medical and industrial areas.
