Question

Cells that provide mechanical strength to the pholem

Answer 1

Answer:

Cytoskeleton is a stable and dynamic proteins that gives the cell shape, structure, and mechanical resistance to deformations. It is extended throughout cytoplasm. All cytoskeletons consist of three major classes of elements that differ in size and in protein composition.

Answer 2
