(4) a. Which one of the following process is responsible for carrying water to the leaves of a tall plant through xylem vessels : a. Transpiration pull b. Root pressure c. b. Absorption through roots Euron The reason for my answer is: a. Due to a force of moving water upward through xylem vessels b. Deficiency of water in the xylem C.

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. Agree, because increase in turgor pressure under this condition, closes the stomates.
