This is the palisade mesophyll, which has specialized for capturing incoming sunlight, rotating chloroplasts to the top of the leaf and then allowing them to regenerate by cycling them toward the leaf's center. These chloroplasts are located near the cell's surface to maximize light absorption. Fewer chloroplasts in the spongy mesophyll because most of the light energy is absorbed by the chloroplasts of the palisade mesophyll. Endangered Species Act B. Chloroplasts are organelles that contain the pigment chlorophyll, which is necessary for photosynthesis. These cells have more chloroplasts than other mesophyll cells, and their chloroplasts are arranged in long, thin stacks. Mesophyll cells are a type of ground tissue found in the plants leaves. Does palisade mesophyll contain chloroplasts? Why not for side collisions and rollovers? The leafs cells are irregularly shaped, as are its leaves. When visible light strikes the leaves of a plant, red and blue wavelengths are absorbed by chlorophyll.
