Colourless plastid responsible for storage of proteins is

Options

A. Amyloplast
B. Aleuroplast
C. Elaioplast
D. None

Answer

**Step-by-Step Solution:**

1. **Understanding Plastids**: Plastids are organelles found in the cells of plants and algae. They are involved in the synthesis and storage of food.

2. **Types of Plastids**: There are several types of plastids, including chloroplasts (which contain chlorophyll and are involved in photosynthesis), chromoplasts (which contain pigments), and leucoplasts (which are colorless).

3. **Focus on Leucoplasts**: Among the different types of plastids, leucoplasts are colorless and primarily involved in the storage of substances. They do not have pigments, which is why they appear colorless.

4. **Function of Leucoplasts**: Leucoplasts are responsible for storing various substances, including proteins, starch, and lipids. However, in the context of the question, we are specifically interested in the storage of proteins.

5. **Conclusion**: The colorless plastid responsible for the storage of proteins is called "leucoplast."

**Final Answer**: Leucoplast
