Process by which water diffuses from the stomata and into the airspaces surrounding the plant
Transpiration
1 of 11
The 'force' created as water diffuses from the leaves, drawing water through the xylem
Transpiration pull
2 of 11
Water molecules form hydrogen bonds, creating a continuous column of water; this is the main factor responsible for the movement of water up the xylem
Cohesion-tension
3 of 11
These cells lose water through evaporation, giving them a low water potential
Mesophyll cells
4 of 11
Thick-walled, hollow tubes through which the vast majority of water is transported
Xylem vessels
5 of 11
Process by which organic molecules and mineral ions are transported
Translocation
