the cell membrane has to be semi-permeable to allow the selective diffusion of certain substances. the lipids and proteins composition of the membrane allow such diffusion to occur. Lipids are hydrophobic on the outside so that water does not enter in and submerge the cell’s interior. Proteins allow for the active transport of ions and large molecules that are essential to the cell’s growth and development.
