Question

give three function of centrosome in animal cell

Answer 1

Function of Centrosomes. Centrosomes are sometimes referred to as the “MTOC,” or “microtubule organizing center” of the cell. They serve to direct the movements of microtubules and other cytoskeletal structures and proteins, ultimately allowing large changes to the shapes of animal cell membranes

Answer 2

Answer:

The centrosome is made up of two perpendicular centrioles, one for the daughter centriole and one for the mother centriole, which are linked by interconnecting fibres.

               It is a protein complex that aids in the creation of extra microtubules. An amorphous pericentriolar matrix surrounds the centrioles. It contributes to the formation and anchoring of cytoplasmic microtubules.

           The centrosome in animal cells is remarkably similar to DNA.

• One centrosome from the parent cell is transmitted to each daughter cell during cell division.
• The centrosome begins to divide in proliferating cells before the S-phase begins.
• The freshly generated centrosomes help organize the mitotic spindles.
• The centrosome organizes an astral ray of microtubules during interphase, which aids in intracellular trafficking, cell adhesion, cell polarity, and so on.

The centrosome in post-mitotic cells is made up of a mature centriole and an immature centriole, known as the mother centriole and daughter centriole, respectively.

There are four phases to the centrosome cycle:

• The replication of centrosomes occurs during the G1 phase.
• The centrosome matures during the G2 phase.
• During the mitotic phase, centrosomes separate.
• A late mitotic phase in which chromosomal disorientation occurs.

The following are the key functions of the centrosome:

• Centrosomes aid in cell division.
• During cell division, they keep the chromosomal number.
• They also cause changes in the shape of the cell membrane by inducing phagocytosis.
• It aids in the organization of microtubules during mitosis, ensuring that centrosomes are dispersed to each daughter cell.
• They control the movement of microtubules and cytoskeletal structures, allowing for changes in the geometries of animal cell membranes.

Animal Cell Centrosome

Centrosomes are not necessary for most animal cells during cell division, despite the fact that they improve the efficiency of the mitotic spindle arrangement. In humans, centrosome malfunction can promote cancer by increasing the levels of instability in chromosomes or by enhancing cancer cells' capacity to spread. However, there is no proof in the research.
