Functions of Transpiration
| Function | Mechanism | Benefit |
|---|---|---|
| Cooling | Evaporation removes latent heat | Prevents overheating in sunlight |
| Mineral transport | Minerals dissolved in transpiration stream | Delivers nutrients to all cells |
| Water distribution | Creates pull from roots to shoots | Supplies water for photosynthesis |
| Turgor maintenance | Continuous water flow maintains pressure | Keeps non-woody plants upright |
| Concentration of sugars | Water loss concentrates phloem sap | Aids sugar transport |
