TRANSPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The faster the movement of air, the ____ the rate of transpiration.
A
slower
B
faster
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -It is easier for water to evaporate into dryer air than into more saturated air. Increased movement of the air around a plant will result in a higher transpiration rate. If there is no wind, the air around the leaf is still and transpiration raises the humidity around each leaf.

Detailed explanation-2: -Hot temperature, dry and windy environment causes fastest transpiration rate.

Detailed explanation-3: -Transpiration is affected by air movement. As the movement of air increases, the concentration gradient is increased, so the rate of transpiration increases. Transpiration is affected by light intensity. As the light intensity decreases, the stomata close up and there is a reduction in photosynthesis.

Detailed explanation-4: -An increase in wind speed increases the rate of transpiration as water molecules are moved away from the leaf faster.

Detailed explanation-5: -It is a physical process. Transpiration is a slow process.
