Question

how xylem transport water to the leaves which is anti gravity
how this work ?

Answer 1

Transpiration pull: It is an anti gravitational force created due to transpiration or water loss from the leaves which pulls up water from the roots. In tall trees transpiration pull helps to draw water to the tips.

 

Cohesive and adhesive force: These are the additional forces that help water flow through xylem in upward direction. The force of attraction between water molecules are known as cohesive force and the force of attraction between water molecule and cell walls is adhesive force.
