NEET BIOLOGY

Detailed explanation-1: -The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement.

Detailed explanation-2: -Chapter 11The Cytoskeleton and Cell Movement The cytoskeleton provides a structural framework for the cell, serving as a scaffold that determines cell shape and the general organization of the cytoplasm. In addition to playing this structural role, the cytoskeleton is responsible for cell movements.

Detailed explanation-3: -Intermediate filaments consist of several intertwined strands of fibrous proteins. Intermediate filaments have no role in cell movement. Their function is purely structural. They bear tension, thus maintaining the shape of the cell, and anchor the nucleus and other organelles in place.

Detailed explanation-4: -1. Membrane–cytoskeleton anchoring complexes. A basic anchoring complex includes a membrane anchor (ion transport protein or adhesion molecule), a linker (ankyrin or a member of the protein 4.1 family) and a cytoskeletal network of actin and spectrin.
