Abacterium grows by using molecules obtained from its environment to build new molecules. describe how the structure of the plasma membrane aids in the bacterium's ability to exchange necessary materials with its environment.

in 1972 the fluid—mosaic membrane model of membrane structure was proposed based on thermodynamic principals of organization of membrane lipids and proteins and available evidence of asymmetry and lateral mobility within the membrane matrix [s. j. singer and g. l. nicolson, science 175 (1972) 720–731].
