Vedclass · Answer

(A) Some of the cells in the leaves of grasses are comparatively very large,called bulliform or motor cells.These cells are hygroscopic in nature.They are thin-walled and contain large central vacuoles filled with water.When water is lost due to stress,these cells become flaccid,causing the leaves to curl or fold to minimize water loss.When water is available,they become turgid,causing the leaves to unfold.$e.g.$,$Ammophila$.
