Detailed explanation-1: -Most eukaryotic cells contain a complex network of protein fibers called the cytoskeleton. It forms a framework for the movement of organelles around the cytoplasm-most of the organelles are attached to the cytoskeleton. The network consists of protein microfilaments, intermediate filaments, and microtubules.

Detailed explanation-2: -The cytoskeleton is the network of cytoplasmic protein filaments, composed of microtubules (MTs), actin filaments, and intermediate filaments, that provides an internal scaffold to give the cell shape.

Detailed explanation-3: -Cytoskeleton. The cytoskeleton is a network of long fibers that make up the cell’s structural framework. The cytoskeleton has several critical functions, including determining cell shape, participating in cell division, and allowing cells to move.

Detailed explanation-4: -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-5: -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.
