Question

lower and upper epidermis definition ​

Answer 1

Main Difference-Upper Epidermis vs Lower Epidermis Upper and lower epidermis are the two outermost layers of a leaf, which are found in the upper and the lower surfaces, respectively. Leaves are the major structure of plants involved in the production of food by photosynthesis. The cells of the leaves consist of photosynthetic pigments such as chlorophyll to capture energy from sunlight. Inorganic molecules are used to produce simple carbohydrates by this energy. Since leaves are the center of photosynthesis, the anatomy of the leaves is built in such a way to facilitate photosynthesis. The structure of upper and lower epidermis aid the process of photosynthesis. Moreover, both types of epidermis help to maintain the water balance of the plant. The main difference between upper epidermis and lower epidermis is that upper epidermis possesses a cuticle layer whereas lower epidermis possesses a large number of stomata.
