- Photosynthesis is a easily overlooked process
How has it adapted to its function?
- Large number of chloroplasts
- Very strong cell wall
- The layer is placed on the top of the leaf to make sure that chloroplasts get maximum light absorption

The typical palisade cell is 30-40 microns wide.

palisade mesophyll cells have more chloroplast ..
A major role of leaf mesophyll cells is to contain large populations of chloroplasts, which carry out photosynthetic carbon assimilation facilitating plant growth.
This layer is made up of palisade cells which contain chloroplasts.
In monocotyledonous leaves, mesophyll cells are not differentiated into two types according to position in the leaf, although those cells circling the vascular tissue form a distinct cell‐type called the bundle sheath cell.
What is the function of leaf palisade cell?
This tissue is called the mesophyll, meaning "middle leaf," and comes in two flavors: the palisade mesophyll (sometimes called palisade parenchyma) and the spongy mesophyll.

On each side of the stoma there is a guard cell with chloroplasts." title="Internal structure of a leaf" height="380" width="546" style="margin-bottom: 0px;">The internal structure of the leaf is also adapted to promote efficient photosynthesis:
loosely arranged beneath the palisade mesophyll ..
The inside of the leaf looks like this:
Spongy mesophyll cells are not packed so tightly together, which allows carbon dioxide and oxygen to reach the palisade cells where they are needed in photosynthesis.
