Cell membranes play a critical role in maintaining homeostasis within cells. They regulate the movement of substances in and out of the cell, ensuring that essential nutrients enter while waste products are expelled. This selective permeability is achieved through various mechanisms, including diffusion, osmosis, and active transport. Understanding these processes is vital for grasping how cells adapt to changes in their environment and maintain their internal equilibrium. Join us as we explore the fascinating functions of cell membranes in just a few moments!
