Solution

The correct option is A Centrosomes
Centrioles occur in the centrosomes.
The centrosome is a cellular organelle which is the main microtubule organizing centre in an animal cell which also regulates the process of cell-cycle.
They are made up of 2 centrioles which are right angled to each other and is composed of a protein known as tubulin.
Its main function is to organize microtubules (spindle fibres) and pull chromatids apart during cell division.
So, the correct answer is 'Centrosomes'.

Q. Sir
How does mitosis occur in plants without centrioles and centrosomes. We are taught that spindle fibres are formed by centrioles moving to opposite poles of the cell and plant cells don't posses centrioles. Then how is the spindle apparatus is formed and constricted to divide the chromatids.

Q. Spindle fibres start forming between centromere and centrioles during:

Q. Spindle fibres are formed between _________ of the chromosome and centrioles.

Q. How many longitudinal peripheral fibres found in a centriole?

As spindle fibres are formed by centrioles during mitosis. But they are absent in plant cells. So who forms spindle fibres in plants in order to carry out mitosis.
