#Unit 2. Cellular Organization

  1. Cells are glued together by their walls, preventing cell sliding, slippage, and motility

  2. The cell wall acts as a cellular “exoskeleton” that controls cell shape and allows high turgor pressures to develop

  3. cell wall acts as a diffusion barrier that exceeds the size and kinds of molecules that can reach the plasma membrane, both through sieving effects and through ionic and covalent interactions

  4. sensory proteins are partly anchored in the cell wall and form a bridge to the plasma membrane
