How is transpiration linked with water transport in plants?
Answer and explanation
Correct answer: It releases water vapour from leaves and creates an upward pull
The governing concept is transpiration pull. Water evaporates from moist cell surfaces inside leaves and exits through stomata as water vapour. This loss lowers water pressure in the leaf and creates tension in the continuous water column. Cohesion between water molecules and adhesion to xylem walls help pull water upward from the roots. Hence option A is correct; the other choices do not describe transpiration.
