The size of the vascular bundle depends upon the size of veins. An epidermal leaf cell is any cell which protects the outside of the leaf. 3. guard cell chloroplast lower epidermis palisade mesophyll. (2018, August 24). Lack of differentiation between the upper and lower parts of the mesophyll may be due to the orientation of the leaves (for example, both sides of the leaf intercept sunlight), their form, and other adaptations. Internally, the loose arrangement of mesophyll tissue allows rapid diffusion of gases 3. The vascular bundle is conjoint, collateral and closed, which is encircled by a single-layered bundle sheath. The numerous small bumps in the palisade parenchyma cells are chloroplasts. Palisade mesophyll cells can contain 30–70 chloroplasts per cell, while stomatal guard cells contain only around 8–15 per cell, as well as much less chlorophyll. They form a protective layer over the leaf. These are cells that are located toward the surface of a plant leaf and are where photosynthesis typically occurs. The internodes of these plants are long, and the size of the leaves is relatively larger with a higher amount of surface area. The’high concentration’ of chloroplast in the mesophyll, especially the palisade of the dorsiventral leaves, helps to trap the solar energy required for the process.
