Leaves have large surface areas to absorb as much light as possible, and are thin for rapid diffusion; also, they contain chlorophyll, essential for photosynthesis.
Most of their stomata are on the underside of the leaf.
starch and oxygen
pine
Maple
Photosynthesis produce hexose sugar and oxygen
Because the leaf structure do not have the ability to store the starch molecules
With regards to its shape, leaf has a flat surface area, increasing its rate of absorption of sunlight.
To meet the different climate and regions of the world.
Palisade cell

Amphistomatous describes a certain type of leaf morphology in drought adapted plants. These plants have stomates (the openings in the epidermis which allow CO2 to diffuse into the leaf) on both sides of the leaf.
the purpose of photosynthesis is to make sugar/energy/food for a plant to live.
