Meaning of Centriolo

What is Centriolo:

The centriole is the central corpuscle of the centrosomes in animal cells. In plant cells, centrosomes do not have centrioles.

The centrosomes, both in animal and plant cells, are the center of organization of microtubules, a structure that is part of the centrioles, chromosomes, flagella, cilia and the cytoskeleton of cells.

The centrioles are located near the cell nuclei and are bound to the cell membrane as they are made of microtubules, one of the structures that maintain the support of the cytoskeleton.

The centrioles are made up of triplets of microtubules that will duplicate and grow to form mature centrosomes, if the cell plans to mitosis.

Each centrosome has 2 centrioles and the moment DNA and its genetic material are duplicated in the form of chromosomes, the centrioles that will form the 2 future centrosomes that will help in the formation of the mitotic spindle, essential for cell division or mitosis.

Therefore, each cell has a centrosome with 2 centrioles. At the time of DNA duplication, the centrosomes and their centrioles are also duplicated.

Centriole function

The centriole is composed of microtubule triplets made of tubulin protein and bound together by supporting proteins. Prior to prophase in mitosis, centrioles can couple and grow to separate into centrosomes for preparation of the mitotic spindle necessary for cell division.
