It is only the green part of the plant, which takes part in

Options

A. Respiration
B. Transpiration
C. Photosynthesis
D. Osmosis

Answer

### Step-by-Step Solution:

1. **Identify the Green Parts of the Plant**:
- The green parts of a plant primarily include the leaves, stems, and sometimes unripe fruits. These parts contain chlorophyll, which gives them their green color.

2. **Understand the Role of Chlorophyll**:
- Chlorophyll is a green pigment found in the chloroplasts of plant cells. It plays a crucial role in photosynthesis by capturing light energy from the sun.

3. **Explain the Process of Photosynthesis**:
- Photosynthesis is the process by which green plants convert carbon dioxide and water into glucose and oxygen using sunlight. This process occurs in the chloroplasts, where chlorophyll is located.

4. **Highlight the Importance of Sunlight**:
- Sunlight provides the energy required for the photosynthesis process. Without light, chlorophyll cannot perform its function of converting carbon dioxide and water into glucose and oxygen.

5. **Conclude the Role of Green Parts in Photosynthesis**:
- Since chlorophyll is only present in the green parts of the plant, it is these parts that are responsible for carrying out photosynthesis. Therefore, only the green parts of the plant participate in this vital process.

### Final Answer:
It is only the green part of the plant which takes part in photosynthesis.
