Detailed explanation-1: -Microtubules help the cell keep its shape. They hold organelles in place and allow them to move around the cell, and they form the mitotic spindle during cell division. Microtubules also make up parts of cilia and flagella, the organelles that help a cell move.

Detailed explanation-2: -In addition to playing this structural role, the cytoskeleton is responsible for cell movements. These include not only the movements of entire cells, but also the internal transport of organelles and other structures (such as mitotic chromosomes) through the cytoplasm.

Detailed explanation-3: -Microtubules and movement The rapid assembly and disassembly of microtubules can physically move vesicles and cell organelles. Microtubules can locate them within the cell, hold them in position and re-locate them.

Detailed explanation-4: -The cytoskeleton organizes other constituents of the cell, maintains the cell’s shape, and is responsible for the locomotion of the cell itself and the movement of the various organelles within it.

Detailed explanation-5: -Microtubules are found in the interior of the cell where they maintain cell shape by resisting compressive forces. Intermediate filaments are found throughout the cell and hold organelles in place.
