Question

what is difference between microtubules and microfilaments

Answer 1

The primary types of fibers comprising the cytoskeleton are microfilaments,microtubules, and intermediate filaments. Microfilaments are fine, thread-like protein fibers, 3-6 nm in diameter. They are composed predominantly of a contractile protein called actin, which is the most abundant cellular protein.

Answer 2

1) Microtubules - Composed of subunits of protein tubulin.It is Stiff and resist bending . It helpsin cell functions such as mitosisand various cell transport functions
2)Microfilaments - Double Helix composed of contractile protein called actin. Resist buckling and help in cell movement.
I hope it's helps u alot plZ marks as brilliant answer
