WebA respiratory organ consists of a surface across which gas exchange by diffusion can occur between blood and either water or air The surface must be • moist enough to allow the cells to live • large enough to permit sufficient gas exchange • thin enough to permit rapid diffusion In respiration Web15 aug. 2024 · In photosynthesis, plants use carbon dioxide, water, and sunlight to produce glucose, water, and oxygen. Glucose is used as a food source, while oxygen and water vapor escape through open stomata into the surrounding environment. Carbon dioxide needed for photosynthesis is obtained through open plant stomata.
