The rate of temperature is reduced with

Options

A. Increase in temperature
B. Decrease in light intensity
C. Increase in wind velocity
D. Increase in water uptake

Answer

**Step-by-Step Solution:**

1. **Understanding Transpiration**: Transpiration is the process by which water vapor is lost from the aerial parts of plants, primarily through small openings called stomata.

2. **Analyzing the Options**:
- **Option 1: Increase in Temperature**: Increasing temperature generally increases the rate of transpiration because warmer air can hold more moisture, leading to more water loss.
- **Option 2: Decrease in Light Intensity**: Lower light intensity can lead to the closing of stomata, which reduces transpiration. This is because stomata usually open in light to allow for gas exchange during photosynthesis.
- **Option 3: Increase in Wind Velocity**: Higher wind velocity can increase transpiration as it removes the moisture-laden air around the stomata, creating a gradient that promotes more water loss.
- **Option 4: Increase in Water Uptake**: Increasing water uptake generally leads to increased transpiration, as more water is available for the plant to lose.

3. **Conclusion**: Among the options provided, the only factor that can reduce the rate of transpiration is a decrease in light intensity. Therefore, the correct answer is **Option 2: Decrease in Light Intensity**.
