Question

What are centrioles like?

Answer 1

Centrioles:

1. Centrioles are rod-shaped organelles.
2. They are made up of 9 bundles, each of which has 3 microtubules. Centrosomes are made up of two perpendicularly positioned centrioles and their encircling proteins.
3. When a cell divides, these centrioles play a crucial role in lining up the mitotic spindles and separating the chromosomes.
4. The centrioles and basal bodies act as hubs for arranging microtubules.
5. Outside of the nuclear envelope, centrioles produce the microtubules that make up the spindle apparatus employed in cell division.
6. Basal bodies, which organise the growth of each cilium and flagellum, are visible at their bases.
