TRANSPIRATION, COHESION, ADHESION, AND

ROOT PRESSURE!

transpiration

Cohesion and Adhesion

Root pressure

Transpiration: evaporation from the leaves creates a pull that draws water up through the stem.

Gravity: food from photosynthesis is pulled down to nourish the plant.

cohesion: water and minerals cling to each other.

adhesion: water molecules cling to the walls of xylem. This causes tension that forces water and nutrients to rise up the stem.

root pressure: pushes water and minerals up.
