Photosynthesis and Leaf Structure

The Organelle in the palisade layer is the Chloroplast.

Leaves are extremely intricate and complex, creating a system that makes itself sustainable. Let's start with the first layer of the leaf. The cuticle. The cuticle is protector of the leaf and it will allow absorption and will not allow evaporation to occur on its surface. Next is the epidermis which serves as another layer of protection. Now the juicy part of the leaf under the cuticle and epidermis is the palisade mesophyll. It's the juicy part because it does the majority of light absorption.

In the leaf we have the stoma, that is just an opening that lets gas and vapers out. Surrounding the stoma is the guard cell which controls the gas exchange. The meat of the leaf is the spongy mesophyll. It serves as a storage area for things such as sugars and amino acids. In the meat of the leaf there are tube like structures called the Xylem and Pholem. You could compare it to a transportation system, but for the leaf. The 2 transport food.

Last but certainly not the least we have the chloroplast which I consider the most important in fact. The whole leaf would be rendered useless without the power the chloroplast provides for the whole leaf.

Just remember, each piece of the leaf is incredibly useful towards its survive-ability. Each serve its part of photosynthesis but most importantly is the chloroplast which has the ability to turn light into food.
