Vedclass · Answer

(A) The ascent of sap is primarily explained by the cohesion-tension-transpiration pull model.$Statement-I$ is correct: Due to the continuous loss of water through transpiration from the leaves, a negative pressure (tension) is generated in the xylem vessels, which pulls the water column upwards.$Statement-II$ is correct: The xylem sap contains dissolved minerals and solutes, which contribute to a high osmotic pressure, helping in the movement of water across cell membranes.Therefore, both statements are correct.

Given below are two statements about the ascent of sap in plants.
$Statement-I$: Under normal conditions, the sap in the xylem cells shows negative hydrostatic pressure.
$Statement-II$: It also shows high osmotic pressure.
In the light of the above statements, select the correct option given below:
