Question 1:One of the functions of the cytoskeleton in animal cells is to give shape to the cell. Plant cells have a frigid cell wall surrounding the plasma membrane; does the rigid cell wall make a cytoskeleton unnecessary for a plant cell? Defend your answer in terms of other functions of the cytoskeleton.

The cytoskeleton is unique to eukaryotic cells. It is an active three-dimensional structure that fills the cytoplasm. This formation acts as both muscle and skeleton, for movement and firmness. The long fibers of the cytoskeleton are polymers of subunits. The main types of fibers comprising the cytoskeleton are microfilaments, microtubules, and intermediate filaments. Following are the functions of Cytoskeleton:

  • The cytoskeleton provides shape or support for the cell. . The cytoskeleton acts as both a frame and a muscle. Some cells do not have cell walls, and the cytoskeleton determines the shape of the cell, especially the intermediate filaments.
  • The cytoskeleton allows for cells to move. Shape. The sliding, meeting, and disassembly of actin and microtubules cause cell movement. The microtubules and the actin can move organelles place to place within a cell. The moving method of endocytosis requires the cytoskeleton.
  • The cytoskeleton provides a highway system within a cell for the movement of material from one area of the cell to another area of the same cell.
  • The cytoskeleton helps the cell acquire particles. For the process of phagocytosis, the cytoskeleton helps the cell move liquid into the cell, and in the process of pinocytosis, the cytoskeleton helps the cell move large particles into the cell.
