Which of the following organelles stores proteins?

Options

A. Amyloplasts
B. Aleuroplasts
C. Plastids
D. Elaioplasts (oleosomes)

Answer

To determine which organelle stores proteins, we can follow these steps:

1. **Understand the Function of Organelles**: Begin by reviewing the functions of various organelles, particularly those involved in storage within the cell.

2. **Identify Types of Plastids**: Recognize that plastids are a type of organelle found in plant cells, and they can be categorized into three main types: Chloroplasts, Chromoplasts, and Leucoplasts.

3. **Differentiate Between Plastid Types**:
- **Chloroplasts**: These are responsible for storing green pigments and are involved in photosynthesis.
- **Chromoplasts**: These store pigments other than green, such as carotenoids, which give red, yellow, or orange colors.
- **Leucoplasts**: These are colorless plastids that store nutrients.

4. **Focus on Leucoplasts**: Leucoplasts can be further divided into three types based on what they store:
- **Amyloplasts**: Store starch.
- **Alluroplasts**: Store proteins.
- **Allioplasts (Oleosomes)**: Store oils and fats.

5. **Analyze the Options**: Given the options, we can eliminate those that do not store proteins:
- **Amyloplast**: Stores starch (not proteins).
- **Alluroplast**: Stores proteins (this is the correct answer).
- **Chloroplast**: Involved in pigment storage and photosynthesis (not proteins).
- **Allioplast**: Stores oils and fats (not proteins).

6. **Conclude the Answer**: Based on the analysis, the organelle that stores proteins is the **Alluroplast**.

### Final Answer:
The organelle that stores proteins is the **Alluroplast**.
