Vedclass · Answer

(D) Stomata are small pores present on the epidermis of leaves and other aerial parts of plants,which facilitate gas exchange and transpiration.In submerged hydrophytes (plants that grow completely underwater),stomata are absent because gas exchange occurs directly through the general body surface via diffusion in the water.Therefore,the correct option is $D$.
