Question

Are prokaryotic flagella made of microtubules?

Answer 1

Microtubules:

1. They are microscopic, hollow tubes made of alpha & beta-tubulin (a part of the cytoskeleton).
2. They extend throughout the cell, thus providing proper shape & structure to the cell.
3. They also help in cell movement, cell division & cell transport.
4. They are found in eukaryotic cells.

Flagella:

1. These microscopic hair-like appendages help the cell in locomotion.
2. Prokaryotic flagella are made up of a protein called flagellin and not microtubules.
