A
Explains how water moves up the xylem
2
Q
- Cohesion
A
Water molecules are cohesive due to hydrogen bonding
3
Q

As water evaporates from leaves (transpiration) it pulls the column of water up the xylem due to tension created.
4

A
Adhesion between water molecules and the xylem created also helps to maintain the continuous column.
