Permeable biology definition
WebThe permeability of a membrane is dependent on the organization and characteristics of the membrane lipids and proteins. In this way, cell membranes help maintain a state of homeostasis within cells (and tissues, organs, and organ systems) so that an organism can stay alive and healthy. WebApr 5, 2024 · A semi-permeable membrane is a thin layer that allows certain substances to pass through it, while preventing the passage of other substances. It is mostly found in living organisms where it plays a crucial role in maintaining the balance of substances within cells. The word semi-permeable means that the membrane is selective in allowing ...
