Vedclass · Answer

(B) Transpiration pull is the suction force generated in the xylem vessels due to the loss of water vapor from the leaves through stomata. For this process to be effective, the following conditions are required: $1$. $Open 	ext{ stomata}$: This allows the escape of water vapor into the atmosphere. $2$. $Warm 	ext{ air}$: This increases the rate of evaporation, thereby increasing the pull. $3$. $Wet 	ext{ soil}$: This ensures that there is sufficient water available for the roots to absorb, maintaining the water column continuity. Therefore, the correct combination is $Open 	ext{ stomata}$, $warm 	ext{ air}$, and $wet 	ext{ soil}$.
