Answered by GPT-5 mini AI
Bright, sunny light — Increase
Brief reason: Light opens stomata for photosynthesis and raises leaf temperature, increasing the vapor-pressure difference that drives water loss.

Very high humidity — Decrease
Brief reason: High humidity lowers the vapor-pressure deficit between leaf interior and air, so less driving force for transpiration.

Strong, dry wind — Increase
Brief reason: Wind removes the moist boundary layer around the leaf and raises the vapor-pressure gradient, speeding evaporation and water loss.
