A Photomicrograph of the mantle edge of unexposed snails showing single epithelial layer (arrow), unicellular glands with acidophilic secretory materials (a), unicellular glands with basophilic secretory materials (b), and connective tissue (ct). B Photomicrograph of the mantle edge of snails exposed to UV-A radiation for 3 h for two successive days showing separation of the epithelial layer (arrow), unicellular glands with acidophilic secretory material (a), and the unicellular glands that have basophilic secretory material increased in size and number (b). C Photomicrograph of snails exposed to UV-A radiation for 3 h for three successive days showing ruptured epithelial layer with disintegrated cells (arrows) and glands with basophilic secretory materials (b)
