The purpose of the cell membrane
WebbBiological membranes have three primary functions: (1) they keep toxic substances out of the cell; (2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and … WebbA cell wall, not just of bacteria but for all organisms, is found outside of the cell membrane. It’s an additional layer that typically provides some strength that the cell membrane lacks, by having a semi-rigid structure. Both gram positive and gram negative cell walls contain an ingredient known as peptidoglycan (also known as murein ).
