1. Leaves contain numerous chloroplasts which help in photosynthesis;
2. Leaves have palisade cells which trap a lot of energy from the sun for photosynthesis;
3. Leaf veins contain xylem which transport water and mineral salts
4. phloem transport synthesised food;
5. Laves have guard cells regulate the entry of carbon dioxide and exit of oxygen and water vapour by opening the stomata;
6. Leaves are broad and flat to expose a large surface area to sunlight in order to trap a lot of energy; A few cells thick for gases to easily diffuse into photosynthesis cells;
7. They have numerous air spaces to allow free diffusion of the gases;
