Define centrioles.

Hint: Centrioles are animal and plant cells. Cells are considered to have centrioles. These centrioles helped the cell during the cell division. Centrioles works during the process of mitosis as well as in the process of meiosis.

Complete answer:
The answer is as under -
Centrioles are found in almost all eukaryotic animal cells., These are found in protozoan protists, as well as in fungi. The cells of these eukaryotic plants at present in the life cycle.
Centrioles are absent in the angiosperms, gymnosperms, And in some species of algae as well as fungi. The centrals are set of small microtubes. That are very well arranged. There are a total 9 groups of micro tubes. These centrioles are mostly found in pairs and move towards the poles of the nucleus.

Centrioles helps in cell division by forming microtubule organizing centres. These centrioles can be transformed into basal bodies. Basal bodies in the centrioles give rise to Cilia and flagella. This entry can be duplicated. When the new daughter centrioles grow from the proximal. The new Central grows at its own front of existing centrioles, they are known as mother centrioles.

Note: Centrioles are located in the animals. This entry was held in the cell division in the animals. Centrioles are active during the both processes of mattresses as well as melanosis. centrioles are at present in some of the animals or plants that are angiosperms and gymnosperms etc.
