Solution (By Examveda Team)

Of the total water uptake by a plant, passive absorption of water accounts for 98%.
Passive absorption occurs due to osmosis usually when the rate of transpiration is typically higher than normal. In this way, water is transported from the roots to the leaves of the plants through the xylem tissue.
It occurs more rapidly because of the transpiration pull and by the action of cohesive and adhesive force in water molecules that enables the continuous flow of water.
