Question

How does water rise in tall trees?

Answer 1

Root pressure supplies most of the force pushing water at least a small way up the tree. Root pressure is created by water moving from its reservoir in the soil into the root tissue by osmosis 

Answer 2

Due to transpiration (evaporating excess amount of water through leaves) there exists a pulling mechanism which pulls the water from posterior part to all the upper parts

nearly 70%water is lost through transpiration
