The diagram shows structures in the epidermis of a plant leaf.
stoma
guard cell
vacuole
What would most likely happen to the structures in the diagram if the plant experienced a drought?
OA. The vacuoles would fill with oxygen so photosynthesis could continue.
OB. The guard cells would keep the stoma open so photosynthesis could continue.
OC. The guard cells would close the stoma to limit transpiration.
OD. The vacuoles would fill with water to limit transpiration.
