Explain why it is usually difficult to demonstrate respiration in green plant?

Explanation

### Step-by-Step Solution:

1. **Understanding the Processes**:
- Green plants perform two essential processes: photosynthesis and respiration.
- Photosynthesis occurs in the presence of sunlight, where plants take in carbon dioxide (CO2) and water (H2O) to produce glucose and oxygen (O2).
- Respiration is the process where plants take in oxygen and release carbon dioxide, breaking down glucose to release energy.

2. **Gaseous Exchange**:
