      Chapter 5 Membrane Structure and Function. The complex structure and function of the plasma membrane are described, along with the macromolecules that comprise the membrane. The mechanisms by which substances move in and out of cells are discussed, as are the general chemical processes of diffusion and osmosis.

      What is the structure, function, and location of vacuoles? Vacuoles are larger versions of vesicles (membrane-bound sacs with various functions) Food vacuoles form by the engulfment of food particles by the cell membrane (which pinches in to form a membrane sac containing the food particles).
