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 which type of plastid in a plant cell is known to store oils and fats, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Plastids**:
- Plastids are organelles found in plant cells and are involved in the storage and synthesis of various substances. The main types of plastids include:
- Chloroplasts: Contain chlorophyll and are involved in photosynthesis.
- Chromoplasts: Contain pigments that give color to fruits and flowers.
- Leucoplasts: Colorless plastids that store nutrients.

2. **Identify the Function of Each Plastid**:
- **Chloroplasts**: Involved in photosynthesis; they contain chlorophyll.
- **Chromoplasts**: Store pigments (like carotenoids) that provide color to plants; they do not store oils or fats.
- **Leucoplasts**: These can be further divided into different types:
- **Amyloplasts**: Store starch (a carbohydrate).
- **Elaioplasts**: Specifically store oils and fats.

3. **Focus on the Requirement of the Question**:
- The question specifically asks for the plastid that stores oils and fats. From our understanding, we know that Elaioplasts are the type of leucoplast that serves this function.

4. **Select the Correct Answer**:
- Based on the information gathered, the correct answer to the question is **Elaioplast**.

### Final Answer:
The plastid known to store oils and fats in a plant cell is called **Elaioplast**.
