Detailed explanation-1: -The cytoskeleton is a structure that helps maintain cell shape, 1–6 organizes and transports organelles, 1, 7–12 provides mechanical support, 1, 5, 13–16 and allows for cell division and movement.

Detailed explanation-2: -They function both to determine cell shape and in a variety of cell movements, including some forms of cell locomotion, the intracellular transport of organelles, and the separation of chromosomes during mitosis.

Detailed explanation-3: -Microtubules are responsible for a variety of cell movements, including the intracellular transport and positioning of membrane vesicles and organelles, the separation of chromosomes at mitosis, and the beating of cilia and flagella.

Detailed explanation-4: -Microtubules play an important role in a number of cellular processes. They are involved in maintaining the structure of the cell and, together with microfilaments and intermediate filaments, they form the cytoskeleton. They also make up the internal structure of cilia and flagella.

Detailed explanation-5: -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.
