Photosynthesis:
It enables through leaves. Photosynthesis is the process by which leaves absorb light and carbon dioxide to produce carbohydrate (food) for plants to grow. Leaves further adapted to carry out their function.
Function of leaf: Carry out photosynthesis.
Features:
Adaptation & Purpose
1) Chlorophyll : Absorb sunlight to transfer energy into chemicals
2) Stomata : Allow CO2 to diffuse into the leaf
3) Network of veins: To support the leaf and transport water and carbohydrates
4) Thin: Shortened distance for CO2 to diffuse into leaf cells
5) Large surface area: To absorb more light
Inside the Leaf:
*the internal structure sustains efficient photosynthesis*
Structure:
Adaptation & Purpose
1)Thin cuticle made of wax: To protect the leaf without blocking out the light
2) Spongy layer: Air spaces allow CO2 to diffuse through the leaf, increasing the surface area
3)Thin and transparent Epidermis: To allow more light to reach the palisade cells
4) Palisade cell layer at top of the leaf: Absorb more light
5) Palisade cells containing many chloroplasts: To absorb all available light possible
