In flowering plants and ferns, two different layers make up the mesophyll: The upper, palisade layer captures most of the sunlight and carries out most of the photosynthesis. The key difference between palisade parenchyma and spongy parenchyma is that palisade parenchyma consists of columnar cells which are compacted tightly below the upper epidermis of a leaf while spongy parenchyma consists of rounded cells which are loosely arranged below the palisade parenchyma. Comparison of the response in direct vs. diffuse solar radiation. (Adoxaceae) Moreover, the functional significance of palisade tissue may be related to the amount of collimated light within the natural environment. The palisade cells are the main site of photosynthesis, as they have many more chloroplasts than spongy mesophylls, and also have several adaptions to maximise photosynthetic efficiency; Large Vacuole - Restricts chloroplasts to a layer near the outside of the cell where they can be reached by light more easily.
