When will green tomatoes turn red

Options

A. New chloroplasts are made
B. Chloroplasts are disintegrated and converted into chromoplasts
C. Carbon assimilation will not occur
D. Respiration will not take place

Answer

To answer the question "When will green tomatoes turn red?", we need to analyze the options provided and understand the biological processes involved in the ripening of tomatoes.

**Step 1: Understand the Color Change in Tomatoes**
- Green tomatoes contain chlorophyll, which gives them their green color. As tomatoes ripen, they undergo a transformation that leads to a change in color from green to red.

**Step 2: Evaluate the Options**
1. **New Chloroplasts are made**: This option is incorrect because the formation of new chloroplasts does not lead to the ripening process. Instead, chloroplasts are involved in photosynthesis.

2. **Chloroplasts are disintegrated and converted to chromoplasts**: This is the correct option. As tomatoes ripen, chloroplasts break down and are transformed into chromoplasts, which contain pigments like carotenoids that give ripe tomatoes their red color.

3. **Carbon assimilation will not occur**: This option is incorrect. Carbon assimilation is a process that occurs during photosynthesis, but it is not directly related to the color change of tomatoes.

4. **Respiration will not occur**: This option is also incorrect. Respiration is a vital process that continues during the ripening of tomatoes and is essential for their development.

**Step 3: Conclusion**
- The correct answer to the question is that green tomatoes turn red when chloroplasts are disintegrated and converted to chromoplasts.
