For demonstration of Photosynthesis experiments , usually aquatic plant Hydrilla is used not any terrestrial plant, why?

Options

A. It carries out faster Photosynthesis
B. `O_2` released throughout and can accumulate over the water
C. It respires slowly
D. None of the above

Answer

### Step-by-Step Solution:

1. **Understanding Photosynthesis**: Photosynthesis is the process by which green plants, including aquatic plants, convert light energy into chemical energy, producing glucose and oxygen as byproducts.

2. **Choosing the Right Plant**: For demonstration experiments, aquatic plants like Hydrilla are preferred over terrestrial plants. This is primarily due to the ease of observing the oxygen produced during the photosynthesis process.

3. **Characteristics of Hydrilla**:
- **Aquatic Nature**: Hydrilla is an aquatic plant, which means it lives in water. This allows it to be submerged and still perform photosynthesis.
- **Small Size**: Hydrilla is a small plant, making it easy to handle and observe in a laboratory setting.

4. **Oxygen Release**: During photosynthesis, Hydrilla releases oxygen (O2) into the water. This oxygen accumulates at the surface of the water, making it easy to measure and observe the amount of oxygen produced.

5. **Comparison with Terrestrial Plants**: If a terrestrial plant were used for the demonstration, the oxygen produced would be released into the air. This would make it more challenging to observe and measure the oxygen output, as it would disperse quickly into the atmosphere.

6. **Conclusion**: The primary reason for using Hydrilla in photosynthesis experiments is that the oxygen released during photosynthesis can be easily observed as it accumulates on the surface of the water, providing clear evidence of the process.

### Final Answer:
Aquatic plants like Hydrilla are used for photosynthesis experiments because they allow for easy observation of oxygen release, which accumulates on the surface of the water, making it simpler to demonstrate the process compared to terrestrial plants.
