The plastid which can form all other types of plastids is

Options

A. Leucoplast
B. Amyloplast
C. Choroplast
D. Chromoplast

Answer

**Step-by-Step Solution:**

1. **Understanding Plastids**: Plastids are double membranous organelles found in plant cells. They play a crucial role in the storage and synthesis of various substances.

2. **Types of Plastids**: There are three main types of plastids:
- **Chloroplasts**: These are green plastids involved in photosynthesis.
- **Chromoplasts**: These plastids are responsible for the colors in plants, other than green.
- **Leucoplasts**: These are colorless plastids that do not contain pigments and are typically found in non-photosynthetic parts of the plant, such as roots and stems.

3. **Function of Leucoplasts**: Leucoplasts are primarily involved in the storage of substances. They can be modified into three specific types:
- **Amyloplasts**: Store carbohydrates (starch).
- **Alluroplasts**: Store proteins.
- **Elaioplasts**: Store fats.

4. **Identifying the Plastid that Can Form All Others**: Since leucoplasts can differentiate into amyloplasts, alluroplasts, and elaioplasts, they are considered the precursor or the plastid that can form all other types of plastids.

5. **Conclusion**: Therefore, the plastid that can form all other types of plastids is **Leucoplast**.

**Final Answer**: The plastid which can form all other types of plastids is **Leucoplast** (Option 1).
