The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Photosynthesis**: Photosynthesis is the process by which plants make their own food using sunlight, carbon dioxide, and water. It primarily occurs in the leaves. 2. **Identifying Key Components**: The essential components required for photosynthesis are: - **Sunlight**: Provides the energy needed for the process. - **Carbon Dioxide (CO2)**: Absorbed from the atmosphere through the stomata in the leaves. - **Water (H2O)**: Absorbed by the roots and transported to the leaves. 3. **Role of Chlorophyll**: Chlorophyll is a green pigment found in the chloroplasts of plant cells. It is crucial for photosynthesis because it absorbs sunlight and converts it into chemical energy. 4. **Evaluating Options**: The question asks which component's absence would prevent photosynthesis from occurring. We need to analyze the given options: - **Option 1: Guard Cells**: These cells help regulate water loss but are not directly involved in the photosynthesis process. Their absence does not stop photosynthesis. - **Option 2: Chlorophyll**: This is essential for absorbing sunlight. Without chlorophyll, photosynthesis cannot occur. - **Option 3: Vacuole**: Vacuoles are involved in maintaining water balance but do not directly participate in photosynthesis. - **Option 4: Space Between Cells**: This is not a necessary component for photosynthesis. 5. **Conclusion**: The absence of chlorophyll (Option 2) will prevent photosynthesis from occurring in leaves, as it is essential for capturing sunlight. **Final Answer**: Photosynthesis will not occur in leaves in the absence of **Chlorophyll** (Option 2). ---
