Microtubules are found in all of the followings, except-
ব্যাখ্যা
***Microvilli has core of microfilaments.
Microtubules:
Microtubules are non-branching hollow tubules made up of tubulin proteins (∝ and ß tubulin) with a diameter of 25 nm.
Locations:
· Cilia
· Flagella
· Centrioles
. Mitotic spindle
· Elongating cell processes and
· Growing axons
Functions:
1. Movement of cilia, flagella (tail of sperm)
2. Intracellular transport of vesicles
3. In cell division, formation of mitotic spindle
4. Maintenance of cell shape
