Potometer is used to study :

Options

A. Photosynthesis
B. Growth
C. Geotropism
D. Transpiration

Answer

**Step-by-Step Text Solution:**

1. **Understanding Potometer**: A potometer is an instrument used to measure the rate of water uptake by a plant, which is closely related to the process of transpiration.

2. **Analyzing Options**:
- **Option 1: Photosynthesis**: This option is incorrect. Photosynthesis is typically studied using a photobioluminometer, which measures light intensity and its effect on photosynthesis.
- **Option 2: Growth**: This option is also incorrect. Growth measurement in plants is usually done using a Cresco graph, not a potometer.
- **Option 3: Geotropism**: This option is incorrect as well. Geotropism refers to the growth of plants in response to gravity and is not measured using a potometer.
- **Option 4: Transpiration**: This is the correct option. A potometer is specifically designed to study transpiration, which is the process of water vapor loss from plant surfaces.

3. **Conclusion**: The potometer is primarily used to study transpiration in plants, making option 4 the correct answer.

**Final Answer**: The potometer is used to study transpiration.
