Answer:
The correct option is : b. centrosome
Explanation:
Centrosome is a cell organelle, which acts as the microbule organizing center and also regulates the cell cycle progression in an eukaryotic cell.
During the prophase stage of the cell cycle, the centrosomes are associated with the membrane of the nucleus. The nuclear membrane ruptures during the mitosis and the interaction of the centrosome nucleated microtubules with the chromosomes leads to the formation of the mitotic spindle.
Therefore, mitotic spindles arise from the centrosome.
The structure formed during the cell cycle splits copied chromosomes in the cells are called mitotic spindles. They arise from the centrosome.
What is centrosome?
Centrosomes are the cell organelles that act in cell division and are the microtubule-organizing sites. They help in maintaining and regulating the progression of the cell cycle.
Centrosomes and the centrioles vary as the latter is contained in the former structure of the cell. The structure of the centrosome comprises the centrioles and the microtubules.
It majorly organizes the microtubules assembly in the cell and helps in maintaining the cell structure. During the cell cycle phases, they pull and separates the chromatids.
Therefore, option B. centrosome is the structure from which the mitotic spindles arises.
