Adaptations of a leaf to carry out photosynthesis In order to carry out photosynthesis, the leaf needs: A path for transport of glucose and water to the other parts of a leaf. Specialised animal cells. Palisade cells contain the largest number of chloroplasts per cell, which makes them the primary site of photosynthesis in the leaves of those plants that contain them, converting the energy in light to the chemical energy of carbohydrates. Adaptations - Irregular shape, they can change shape to squeeze out of blood vessels and get to the site of infection. Short distance for carbon dioxide to diffuse into leaf cells, Absorbs sunlight to transfer energy into chemicals, To support the leaf and transport water, mineral ions and sucrose (sugar), Allow carbon dioxide to diffuse into the leaf and oxygen to diffuse out. It does this by diffusing through small pores called stomata. Roots absorb water and mineral ions through root hair cells and are transported up the plant by the xylem. The function of a leaf is photosynthesis - to absorb light and carbon dioxide to produce glucose (food). Leaves usually have fewer stomata on their, Leaves enable photosynthesis to occur. Some of this water evaporates, and the water vapour can then escape from inside the leaf. interest in GCSE. This movement of gases in opposite directions is called gas exchange.
