WebBefore we go through how the alveoli are adapted for this, it may be useful to remember Ficks Law: the rate of diffusion = (surface area x concentration gradient)/distance of diffusion pathway. Faster diffusion = larger surface area, steeper concentration gradient, and shorter diffusion pathway. WebGas exchange in the leaves occurs through the stomata on the lower epidermis. Most plants, including dicotyledonous plants, use the stoma for gas exchange. Stoma (singular) are openings which allow for the exchange of carbon dioxide and oxygen. They are opened by ions (mainly K+) which move in via active transport, which allows water loss ... rasadnik iva koprivnica
