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.
Because the leaf structure do not have the ability to store the starch molecules
starch and oxygen
pine
Maple
Photosynthesis produce hexose sugar and oxygen
With regards to its shape, leaf has a flat surface area, increasing its rate of absorption of sunlight.
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 large surface area and the presence of the stomata is the special structural character that the leaf epidermis possess to perform its functions effectively.
A mesophyll is the inner tissue or parenchyma of a leaf, which contains many chloroplasts. The chloroplasts are organelles that perform photosynthesis.
The function of a plant leaf is to provide a structure in which chloroplasts can be exposed to sunlight so that they can perform photosynthesis.
if you extratct the oxygen of leaf disks and put them on water in a well lit environment, and they sink at first but later rise, that would prove that photosynthesis occurs in plants because oxygen is a product of photosynthesis abd would help the disks float
It regenerates itself
