Epidermal cell types in arabidopsis rosette leaf. A schematic diagram of an arabidopsis rosette leaf (left). Hydathode water pores are found at/near the tip of the leaf edges and are typically paired large stomata that remain open (top right). Epidermal pavement cells, trichomes and stomata (right) are found on the leaf blade throughout. Trichomes are only found on the adaxial side of the leaf blade, whereas more stomata are located on the abaxial side. Neither stomata nor trichomes differentiate from the epidermis immediately above the midvein.
