Plant Systems Review

When a plant wilts, which of the answer choices is the best description of that process?

• water entering the plant increases the turgor pressure

• water enter and leave the plant at the same rate keeps turgor pressure equal

• lack of water in the soil decreases the turgor pressure

• lack of sunlight decreases the turgor pressure
