Chromoplasts are formed from chloroplasts during

Options

A. Ripening of Tomato
B. Ripening of Chilli
C. Development of Carrot
D. Both A and B

Answer

**Step-by-Step Solution:**

1. **Understanding Chromoplasts and Chloroplasts:**
- Chromoplasts are colored plastids that contain pigments other than green, responsible for the colors in flowers and certain fruits.
- Chloroplasts are green plastids that contain chlorophyll and are primarily involved in photosynthesis.

2. **Conversion Process:**
- During the ripening of certain fruits, chloroplasts can convert into chromoplasts. This process is significant as it changes the color of the fruit, indicating ripeness.

3. **Identifying the Fruits:**
- The question asks about the formation of chromoplasts from chloroplasts during the ripening of specific fruits.
- The options provided are:
- Option 1: Ripening of tomato
- Option 2: Ripening of chili
- Option 3: Development of carrot
- Option 4: Both A and B

4. **Analyzing the Options:**
- The ripening of tomatoes and chilies is known to involve the conversion of chloroplasts to chromoplasts, which leads to the change in color as the fruit ripens.
- The development of carrots does not involve this conversion process as carrots are typically root vegetables and do not exhibit the same chromoplast formation.

5. **Conclusion:**
- Since both the ripening of tomatoes and chilies involve the conversion of chloroplasts to chromoplasts, the correct answer is:
- **Option 4: Both A and B.**
