Question

• A. Rainy season
• B. Sunny Afternoon
• C. Cloudy afternoon
• D. None of the choices

Answer 1

The correct option is B

Sunny Afternoon

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining is lost by transpiration. Transpiration rate is highest during a sunny afternoon.
