It we use upper epidermis, rather than the lower epidermis, what will be the conclusion and why?
It will reduce a plant transpiration. Upper epidermis is a flattened layer of cell that forms the surface of the leaf and makes the cuticle. Lower epidermis: bottom surface layer of tissues which contains the guard cells that form each stoma, which provides transpiration. [ Evert, Ray F; Eichhorn, Susan E.
