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

Quick Recall Flashcards

What is a xerophyte?
A plant adapted to survive in dry/arid conditions with limited water availability (e.g., cacti, marram grass).
What is a potometer?
An apparatus that measures the rate of water uptake by a plant shoot. Used to estimate transpiration rate (though actually measures uptake, not loss).
