Carotenoids are found in
(I) chloroplasts
(II) leucoplasts
(III) vacuole
(IV) chromoplasts

Options

A. I only
B. I and II
C. II and III
D. I and IV

Answer

To determine where carotenoids are found, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Carotenoids**:
- Carotenoids are pigments that produce bright yellow, red, and orange colors in fruits and vegetables. They also have antioxidant properties.

2. **Analyzing Each Option**:
- **(I) Chloroplasts**:
- Chloroplasts are the sites of photosynthesis in plant cells and contain various pigments, including chlorophyll and carotenoids.
- **Conclusion**: Carotenoids are found in chloroplasts. (Correct)

- **(II) Leucoplasts**:
- Leucoplasts are involved in the storage of starches, oils, and proteins. They do not contain pigments and are not involved in photosynthesis.
- **Conclusion**: Carotenoids are not found in leucoplasts. (Incorrect)

- **(III) Vacuole**:
- Vacuoles are storage organelles in plant cells and help maintain cell turgor and volume. They do not synthesize pigments.
- **Conclusion**: Carotenoids are not found in vacuoles. (Incorrect)

- **(IV) Chromoplasts**:
- Chromoplasts are responsible for pigment synthesis and storage, particularly carotenoids, which contribute to the color of fruits and flowers.
- **Conclusion**: Carotenoids are found in chromoplasts. (Correct)

3. **Final Conclusion**:
- Based on the analysis, carotenoids are found in:
- (I) Chloroplasts: Correct
- (IV) Chromoplasts: Correct
- Therefore, the correct answer is that carotenoids are found in **Chloroplasts and Chromoplasts**.

### Final Answer:
Carotenoids are found in **(I) Chloroplasts and (IV) Chromoplasts**.
