Detailed explanation-1: -In the epidermis of leaves, stomata can be observed. Stomata are necessary for gaseous exchange and water vapour loss during transpiration. The bottom side of dicot leaves either has more stomata than the upper side or has stomata just on the lower side.
Detailed explanation-2: -The number of stomata on leaf surfaces varies greatly between various plant species. The leaf’s lower epidermis often has a higher total than the top surface. On average, there are 300 stomata per square mm of leaf surface.
Detailed explanation-3: -Using clear nail varnish is a traditional method to measure stomatal density, since making the impression and viewing it under a microscope can be completed in one lesson. However, some leaves are prone to damage from the solvent in the nail varnish. The leaves absorb it, turn brown, and fail to produce any impression.
