Potomater is used for measuring

Options

A. light intensity
B. growth rate
C. photosynthetic rate
D. transpiration rate

Answer

**Step-by-Step Solution:**

1. **Understanding the Potometer**: A potometer is a device used to measure the rate of water uptake in plants. It is often referred to as a transferometer.

2. **Function of the Potometer**: The primary function of a potometer is to measure how much water a plant absorbs through its leafy shoots. This water uptake is crucial for various physiological processes in plants.

3. **Relation to Transpiration**: The water uptake measured by the potometer is largely due to transpiration, which is the process by which water vapor is lost from the plant leaves to the atmosphere. Transpiration creates a negative pressure that helps pull water up from the roots through the plant.

4. **Identifying the Correct Option**: Given the options:
- Light intensity
- Growth rate
- Photosynthetic rate
- Transpiration rate

Since the potometer measures the rate of water uptake, which is directly related to transpiration, the correct answer is the transpiration rate.

5. **Conclusion**: Therefore, the potometer is used for measuring the transpiration rate in plants.

**Final Answer**: The potometer is used for measuring the transpiration rate.
