Options

A. Aleuroplasts
B. Elaioplasts
C. Amyloplast
D. chromoplast

Answer

To solve the question "Which of the following plastids is colored and contains carotenoids?", we will analyze the options provided and identify the correct plastid based on their characteristics.

### Step-by-Step Solution:

1. **Understand the Options**:
- The options given are:
- a) Alluroblast
- b) Allioplast
- c) Amyloplast
- d) Chromoplast

2. **Define Each Plastid**:
- **Alluroblast**: This is a type of plastid that primarily stores proteins. It does not contain pigments and is not colored.
- **Allioplast**: This plastid is involved in the storage of fats. Like alluroblasts, it does not contain colored pigments.
- **Amyloplast**: This plastid is responsible for the storage of starch (carbohydrates). It is also colorless and does not contain pigments.
- **Chromoplast**: This type of plastid is known for containing colored pigments, specifically carotenoids, which are responsible for yellow and orange colors in plants.

3. **Identify the Colored Plastid**:
- Among the four options, only **Chromoplast** is known to contain colored pigments, particularly carotenoids, which give it its yellow and orange hues.

4. **Conclusion**:
- Therefore, the plastid that is colored and contains carotenoids is **Chromoplast**.

### Final Answer:
The correct answer is **Chromoplast**.
