Palisade cells are plant cells found within the mesophyll in leaves, right below the upper epidermis and cuticle. They are vertically elongated, a different shape from spongy mesophyll cells beneath them in the leaf. Their chloroplasts absorb a major portion of the light energy used by the leaf. Palisade parenchyma cells are present below the upper epidermis in dorsiventral leaf.
Spongy parenchyma cells are present towards the lower epidermis in dorsiventral leaf. These are oval-shaped parenchymatous cells and are loosely arranged with large air chambers.
