Features of Leaves
Large surface area: To absorb more light
Thin: Short distance for carbon dioxide to diffuse into leaf cells
Chlorophyll: Absorbs sunlight to transfer energy into chemicals
Network of veins: To support the leaf and transport water and carbohydrates
Stomata: Allow carbon dioxide to diffuse into the leaf
Structure of Leaves
Epidermis is thin and transparent: To allow more light to reach the palisade cells.
Thin cuticle made of wax:To protect the leaf without blocking out light.
Palisade cell layer at top of leaf: To absorb more light.
Spongy layer: Air spaces allow carbon dioxide to diffuse through the leaf, and increase the surface area.
Palisade cells contain many chloroplasts: To absorb all the available light.
