Question

The trees are greenish. They are greenish at the tip too. How does the water rise upward in a tree or plant against the force of gravity?

Answer 1

1. Water can travel to great heights inside plants. Water moves up the xylem through a process called capillary action.
2. During transpiration, water evaporates from holes in the surface of leaves into the air. As water molecules evaporate from plant leaves, they attract the water molecules still in the plant, helping to pull water up through the stems from the roots.
