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.
