Leaf Adaptations for Photosynthesis

  • Leaves are the plant organs that carry out photosynthesis
  • Their structure is adapted to maximise photosynthesis, e.g.
    • They have a large surface area to maximise light absorption
    • They are thin to allow efficient movement of gases between leaf cells and the surrounding air

How photosynthesising cells obtain carbon dioxide

Leaves are adapted to carry out photosynthesis by being thin; this allows gases to diffuse quickly, e.g. carbon dioxide can diffuse quickly between the surrounding air and the photosynthesising cells of the leaf
