Scanning electron microscopy (SEM) analysis of adaxial leaf epidermis in four plant species under control, drought, and recovery conditions. Representative SEM micrographs show stomatal and epidermal surface features of Triticum aestivum (a–c), Helianthus annuus (d–f), Chenopodium album (g–i), and Alternanthera brasiliana (j–l) under control, drought, and recovery treatments, respectively. Drought stress visibly altered stomatal aperture, wax deposition, and epidermal integrity in all species. Magnifications and scale bars are indicated on each panel.
