The plasma membrane serves as the selective barrier between the intracellular fluid (ICF) and the extracellular fluid (ECF). It is composed of a phospholipid bilayer interspersed with proteins, cholesterol, and carbohydrates. The concept of selective permeability is crucial; the membrane allows the passage of nutrients while retaining vital cell constituents and excluding harmful agents. Transport mechanisms—ranging from passive diffusion and osmosis to active transport via ATP-driven pumps (e.g., the Na+/K+-ATPase pump)—are fundamental to maintaining the concentration gradients essential for cell survival.
