What is the main thing that drives water to move up from roots through the stem or trunk and to the leaves in plants?.

Sagot :

The main thing that drives water to move up from roots through the stem or trunk and to the leaves in plants is evaporation from the leaf pores

As water molecules evaporate from plant leaves, they attract water molecules that remain in the plant, assisting in the water flow from the roots to the stems. The combined effects of capillary action and transpiration transport water from the roots to the leaves of a plant.

Because water molecules tend to grip together (cohesion) and stick to the walls of tubes, they rise from the roots to the leaves (adhesion). The water evaporating from the leaf surface aids the root system's capacity to absorb additional water. This mechanism is known as capillary action.
