WebPlant leaves are adapted for photosynthesis and gas exchange. Roots absorb water and mineral ions through root hair cells and are transported up the plant by the xylem. WebThe lungs are specifically adapted for gas exchange (diffusion) - meaning the lungs allow oxygen into the blood stream and carbon dioxide out. To ensure our cells can respire properly, we want fast and efficient gas exchange. The lungs contain many 'tubes' or airways that carry air in and out of our lungs.
