Detailed explanation-1: -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-2: -Every few seconds, with each inhalation, air fills a large portion of the millions of alveoli. In a process called diffusion, oxygen moves from the alveoli to the blood through the capillaries (tiny blood vessels) lining the alveolar walls.
Detailed explanation-3: -Photosynthesis. When photosynthesis occurs, carbon dioxide diffuses into the leaf through the stomata (pores, or tiny holes, in the leaf) while oxygen moves out of the leaf in the same way. NOTE: stomata is plural, stoma is singular.
