Q

How does water move up through the xylem tissue

A

What are evaporates from inside the leaf leaving a higher concentration of .

water From the nearest xylem Vessel enters by osmosis.

Water molecules stick together. Because of weak hydrogen bonds between them. This is called cohesion

As water molecules. Leave the xylem vessel. They pull further molecules so the whole column of water is pulled up,

Adhesion of. The water molecules to the sides of the xylem vessels stop the col from breaking column
