विकल्प
atmosphere is dry
temperature is high
humidity is high
atmosphere is dry and temperature is high
उत्तर
atmosphere is dry and temperature is high
Explanation:
When the atmosphere is dry, there is low humidity, creating a large difference in water vapour concentration between the inside of the leaf and the surrounding air.
High temperatures increase the kinetic energy of water molecules inside the leaf, speeding up evaporation.
Dry atmospheric conditions and high temperatures maximize transpiration by promoting faster evapouration within the leaf and enhancing water vapour diffusion into the surrounding air.
