Spindle fibre is made up of
Updated On: May 12, 2022
- tubulin
- humulin
- intermediate filament
- flagellin
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Tubulin is a cytoskeletal globular protein that polymerizes to form microtubules. It plays a motile and contractile role in cell structure and cell division. During cell division, the microtubules radiate from each end of the cell form a basket like arrangement (the spindle) which helps in the movement of chromosomes to poles.
The principal protein of cilia and flagella is also tubulin. Microtubules play a key role in the movement of cilia and flagella.
Intermediate filaments are tough rope- like bundles or protein (keratin, desmin, peripherin, vimentin etc). Intermediate filaments provide mechanical stability to cells. They interact with microfilaments (made of protein, actin) and microtubules to form cytoskeleton.

Concepts Used:
Eurkaryotic Cells - Golgi Apparatus
The Golgi apparatus is also known as the Golgi complex or the Golgi body. The term is derived from Camillo Golgi, the scientist who discovered the organelle. It can be found in all eukaryotic cells, including plants and animals. They are membrane-bound organelles found in the cell's cytoplasm.
Formation of acrosome: The acrosome is a component of the tip of animal sperms that aids in the digestion of the egg or ovum covering sheath during fertilisation. The Golgi complex produces it with the help of its vesicles.
