An electron micrograph of a plant cell shows two different types of them is known to store oils and fats in them, such a plastid is known as :

Options

A. Chloroplast
B. Chromoplast
C. Elaioplast
D. Amyloplast

Answer

To solve the question regarding the type of plastid in a plant cell that stores oils and fats, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Plastids**:
- Plastids are specialized organelles found in plant cells that serve various functions, including storage and photosynthesis.

2. **Identifying Types of Plastids**:
- There are three main types of plastids:
- **Chloroplasts**: Contain chlorophyll and are involved in photosynthesis.
- **Chromoplasts**: Contain pigments that give color to fruits and flowers, but do not store oils or fats.
- **Leucoplasts**: These are colorless plastids that primarily store substances.

3. **Classifying Leucoplasts**:
- Leucoplasts can be further divided into three types based on what they store:
- **Amyloplasts**: Store starch.
- **Alluroplast (or Proteinoplast)**: Store proteins.
- **Elioplasts**: Store oils and fats.

4. **Analyzing the Question**:
- The question specifies that the plastid in question is known to store oils and fats.

5. **Conclusion**:
- Based on the classifications, the plastid that stores oils and fats is the **Elioplast**.

### Final Answer:
The plastid known to store oils and fats is called **Elioplast**.
