Detailed explanation-1: -Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products.
Detailed explanation-2: -Diffusion is a very important process for photosynthesis where carbon dioxide from the stomata diffuses into the leaves and finally into the cells. Also, during transpiration, the water and oxygen diffuse from the leaves into the environment.
Detailed explanation-3: -Another example of diffusion in animal cells is the exchange of carbon dioxide and oxygen between the alveoli in the lungs and the blood. See gaseous exchange.
Detailed explanation-4: -Minerals and water diffuse into the plant through the roots. Food molecules diffuse into the blood stream in the small intestine. Water molecule diffuse into the blood stream in the large intestine. Oxygen molecules diffuse into the bloodstream in the lungs.
Detailed explanation-5: -Diffusion refers to the overall movement of particles from areas of high concentration to areas of low concentration. In living things, diffusion allows substances to move in and out of cells. It’s how red blood cells distribute oxygen through the body.
