One of the larger facets of modern zoology can be described as "membrane biology". What common principles unite the diverse functions of membranes?
Membrane biology refers to the study of biological and physicochemical aspects of membranes. All cells, present in a living organism, are bound by a cellular membrane that is selectively permeable. The cell membrane performs various functions like regulating material moving in and out of the cell; separating the inside of the cell from the extracellular environment; separating various organelles within the cell; providing a large surface area for certain chemical reactions to occur and as a site for specific cell identification markers to help differentiate between one type of cell from another.
