| Front | Why is their more tension in the xylem at higher light intensities? |
|---|---|
| Back | - more stomata open - more water evaporates from mesophyll cell walls using heat from Sun - larger wp gradient - more water loss by evaporation - more water drawn up xylem by cohesion - water molecules stick to xylem walls by adhesion - so more tension |
