Answer:
Leaf mesophyll Or The Palisade Layer
Step-by-step explanation:
In plants, chloroplasts are concentrated particularly in the parenchyma cells of the leaf mesophyll (the internal cell layers of a leaf).
The layer it is found is The Palisade Layer. Below the upper epidermis is the palisade layer. This is one or a few layers of cylindrical cells that contain many chloroplasts.
