प्रश्न
Name the factors which affect the rate of transpiration? State their role in each case.
उत्तर
The following are the main factors that affect the rate of transpiration:
- Sunlight: During daytime, the rate of transpiration is faster. This is because the stomata remain open to allow the inward diffusion ofcarbondioxide for photosynthesis.
During dark, the stomata are closed, and hence transpiration hardly occurs at night. - Temperature: Transpiration is faster on hot summer days as compared to cold winter.
- Wind: Transpiration is more when the wind is blowing faster as water evaporates faster from the leaves.
- Humidity: Transpiration is reduced if the air is humid. Air cannot hold any water molecules when it is already laden with moisture (humidity).
- Low atmospheric pressure: The rate of transpiration increases when the pressure is low.
