living organisms obtain many of their requirements by diffusion. they also get rid of their waste products in this way. for example, plants need carbon dioxide for photosynthesis. this diffuses from the air into the leaves, through the stomata. it does this because there is a lower concentration of carbon dioxide inside the leaf, as the cells are using it up. outside the leaf in the air, there is a higher concentration. carbon dioxide molecules therefore diffuse into the leaf, down this concentration gradient
Passive transport is the movement of molecules across a cell membrane without the use of energy. Examples include simple diffusion, where molecules move from an area of high concentration to low concentration, and facilitated diffusion, where molecules pass through a membrane with the help of transport proteins.
