- When absorption of water by the roots fails to keep up with the rate of transpiration, gain in turgor occurs, and the stomata close. A. Agree, because the transpiration occurs faster than root absorption. D. Disagree, because the condition should be when root absorption is able to keep up with transpiration, then stomates close. B. Disagree, because under this condition, the turgor pressure decreases and the stomates close. C.
