Plastids which are responsible for trapping light energy essential for photosynthesis

Options

A. Leucoplasts
B. Chromoplasts
C. Chloroplasts
D. All

Answer

**Step-by-Step Solution:**

1. **Understanding Plastids**: Plastids are double membrane-bound organelles found in plant cells. They play various roles in the cell, including photosynthesis, storage, and pigment synthesis.

2. **Types of Plastids**: There are three major types of plastids:
- **Chloroplasts**
- **Leukoplasts**
- **Chromoplasts**

3. **Function of Chloroplasts**:
- Chloroplasts contain chlorophyll, the green pigment that captures light energy.
- They are essential for photosynthesis, the process through which plants convert light energy into chemical energy (food).

4. **Function of Leukoplasts**:
- Leukoplasts are primarily involved in the storage of food.
- They do not play a role in photosynthesis and are not involved in trapping light energy.

5. **Function of Chromoplasts**:
- Chromoplasts contain colored pigments (like carotenoids) that give fruits and flowers their colors.
- They also do not contribute to photosynthesis.

6. **Conclusion**: Since the question specifically asks for the plastids responsible for trapping light energy essential for photosynthesis, the correct answer is **Chloroplasts**.

7. **Final Answer**: The plastids responsible for trapping light energy essential for photosynthesis are **Chloroplasts**.
