which type of plastid contains chlorophyll and responsible for photosynthesis?

Options

A. chloroplast
B. chromoplast
C. Aleuroplast
D. Elaioplast

Answer

To answer the question, "Which type of plastid contains chlorophyll and is responsible for photosynthesis?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Plastids**:
- Plastids are organelles found in plant cells and are classified into different types based on their function and pigment content.

2. **Identify the Options**:
- The options provided are:
- A) Chloroplast
- B) Chromoplast
- C) Alluroplast
- D) Alleloplast

3. **Analyze Each Option**:
- **Chloroplast**: This type of plastid contains chlorophyll, the green pigment essential for photosynthesis. Chloroplasts are involved in the process of converting light energy into chemical energy (food).
- **Chromoplast**: These plastids are responsible for the pigmentation of fruits and flowers, providing colors like red, yellow, and orange. They do not contain chlorophyll and are not involved in photosynthesis.
- **Alluroplast**: This type of plastid primarily stores proteins. It does not play a role in photosynthesis.
- **Alleloplast**: These plastids are involved in storing fats or lipids. They are also not involved in photosynthesis.

4. **Conclusion**:
- Based on the analysis, the only plastid that contains chlorophyll and is responsible for photosynthesis is the **Chloroplast**.

5. **Final Answer**:
- The correct answer is **A) Chloroplast**.
