Statement I is false but Statement II is true
Statement I is false. Typically, dicot leaves exhibit a greater number of stomata on the abaxial (lower) epidermis compared to the adaxial (upper) epidermis, an adaptation to minimize water loss.
Statement II is true. Palisade parenchyma cells are characterized by their elongated, vertically oriented, and parallel arrangement, which optimizes light absorption for photosynthesis.
