ANATOMY

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: -Two forms of tubulin form dimers (pairs) which come together to form the hollow cylinders. The cylinders are twisted around each other to form the microtubules. Microtubules help the cell keep its shape.

Detailed explanation-3: -The cytoskeleton carries out three broad functions: it spatially organizes the contents of the cell; it connects the cell physically and biochemically to the external environment; and it generates coordinated forces that enable the cell to move and change shape.

Detailed explanation-4: -All eukaryotic cells, including plants, animals, fungi and protists have a cytoskeleton. Even prokaryotes have cytoskeletal proteins, but the components are different than eukaryotic cells.

Detailed explanation-5: -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.
