Detailed explanation-1: -The cytoskeleton of a cell is made up of microtubules, actin filaments, and intermediate filaments. These structures give the cell its shape and help organize the cell’s parts. In addition, they provide a basis for movement and cell division.

Detailed explanation-2: -Three major types of filaments make up the cytoskeleton: actin filaments, microtubules, and intermediate filaments. Actin filaments occur in a cell in the form of meshworks or bundles of parallel fibres; they help determine the shape of the cell and also help it adhere to the substrate.

Detailed explanation-3: -The cytoskeleton is a complex, dynamic network of interlinking protein filaments present in the cytoplasm of all cells, including those of bacteria and archaea. In eukaryotes, it extends from the cell nucleus to the cell membrane and is composed of similar proteins in the various organisms.

Detailed explanation-4: -There are three main types of cytoskeletal polymer: actin filaments, microtubules and a group of polymers known collectively as intermediate filaments. Together, these polymers control the shape and mechanics of eukaryotic cells (Fig.

Detailed explanation-5: -The cytoplasm of eucaryotic cells is spatially organized by a network of protein filaments known as the cytoskeleton.
