PPT-Plasma membrane and Cellular Transport

Plasma membranes Membranes cover the surface of every cell and also surround most organelles within cells They have a number of functions such as keeping all cellular components inside the cell. Diffusion. : The passive movement of particles from a region of high concentration to a region of low concentration until equilibrium is reached. (Molecules still move after equilibrium is reached) .

HOMEOSTASIS. is a state of balance/equilibrium within the cell.. The plasma membrane is a SELECTIVELY PERMEABLE membrane that allows nutrients and wastes to enter and exit the cell.
