Because of their shape (elongated and cylindrical) palisade cells contain many chloroplasts Palisade cells contain 70 percent of all chloroplasts. Chloroplasts are usually large organelles (1 to 10 m) found in plant cells. Palisade mesophyll is also important for regulating the temperature of the leaf, helping to reduce water loss and ensuring photosynthesis occurs at the optimal temperature. Whereas wild-type plants have 80 to 120 chloroplasts per mesophyll cell, the accumulation and regulation of chloroplast (arc) mutants used in this study have between one and about 30 chloroplasts per mesophyll cell (Table III).. Because of the number of air spaces in leaf mesophyll, oxygen and carbon dioxide can be exchanged efficiently. A chloroplast, which is an organelle that helps to photosynthesis, is also produced by mesophyll cells. In chloroplasts, ANU10 associates with thylakoidal membranes. Palisade parenchyma is the upper mesophyll layer of elongated chlorenchyma cells, containing large amounts of chloroplasts. These chloroplasts are located near the cell's surface to maximize light absorption. two membranes The cells in the palisade layer are jam-packed with chloroplasts.
