The key difference between centrosome and centromere is that centrosome is a cell organelle that consists of two centrioles while centromere is a point that joins two sister chromatids of a chromosome together. Cell division is an important process occurring in multicellular organisms.
What is the function of centrosome and centromere?
Centrosome: The centrosome is a cell organelle in the eukaryotic animal cells, acting as a center for the organization of the microtubules. Centromere: The centromere is a constricted region of the chromosome where the two identical sister chromatids are connected.
How many centrioles does a centrosome have?
The centrosome doubles through the cell division and one centrosome with two centrioles goes to each of the daughter cell after mitosis. During prophase, the two newly formed centrosomes go to the opposite poles of the cell. Centrosome plays an essential role in the formation of cilia and flagellum.
What happens to centrosomes during interphase of the cell cycle?
During the interphase of the cell cycle, the centrosomes are often connected with the nuclear membrane. During the division of the cell (mitosis) this membrane breaks apart, the centrosome’s microtubules interact with the chromosomes and build the mitotic spindle. The centrosome duplicates once per cell cycle,…
Where is the centromere located in A telocentric chromosome?
In telocentric chromosomes, the centromere is located at the terminal end of the chromosome. Depending on the number of centromeres present on a chromosome, two types of organisms can be identified: monocentric organisms and holocentric organisms. Organisms with a single centromere per one chromosome are known as monocentric organisms.

Chromosome: It is the chromatin material during mitosis and meiosis which coils and uncoils itself and carry’s all the genetic material and information along it. Centrosome: It is an organelle that is present in the cell and is responsible for the division of the daughter cells in the process of mitosis and meiosis.
What are the functions of centrosomes in mitosis?
1 The centrosomes help in cell division. 2 They maintain the chromosome number during cell division. 3 They also stimulate the changes in the shape of the cell membrane by phagocytosis. 4 In mitosis, it helps in organizing the microtubules ensuring that the centrosomes are distributed to each daughter cell. More items…
What is the function of meiosis?
What is the Function of Meiosis? Meiosis is a process by which a eukaryotic cell reduces its chromosomal content and produces germ cells, also known as gametes or sex cells that are needed for sexual reproduction. This means that a cell with a double set of chromosomes (diploid) is divided in half and ends with a single set of chromosomes …
How does the structure of the centrosome change during cell division?
The structure of the centrosome changes during the different phases of the cell cycle and cell division. Interphase. This stage is the preparatory stage to mitosis, during which the cell grows in size and stores enough energy to undergo cell division by mitosis. DNA is replicated during the S-phase or synthesis phase.
What is the role of the cytosome in cell division?
Assist in cell division during mitosis. They direct the movement of microtubules and cytoskeletal structures, thereby, facilitating changes in the shapes of the membranes of the animal cell. They play a role in mitosis in organizing the microtubules ensuring that the centrosomes are distributed to each daughter cell.

‘Chromosomes store genetic information.’; A peculiar rounded body lying near the nucleus of a cell. It is regarded as the dynamic element by means of which the machinery of cell division is organized. One of the minute bodies into which the chromatin of the nucleus is resolved during mitotic cell division; the idant of Weismann.

In general, each centriole of the centrosome is based on a nine triplet microtubule assembled in a cartwheel structure, and contains centrin, cenexin and tektin. Each mitotic cell has two centrosomes and four centrioles (two per centrosome).
