what is the waxy layer of cells
Now that we have looked at the first two layers of the leaf, let's add these structures on our diagram. The top waxy layer here is the cuticle and the layer right below that is the upper epidermis. 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. Chloroplasts are an important part of plant cells because they are cell structures that allow for photosynthesis.
