Polymorphic cell organelle is

Options

A. Vacuole
B. Lysosome
C. Golgi bodies
D. Endoplamic reticulum

Answer

### Step-by-Step Solution

1. **Understanding the Term "Polymorphic"**:
- The term "polymorphic" refers to the ability of an organelle to exist in multiple forms or shapes.

2. **Identifying Polymorphic Organelles**:
- Among the options provided (vacuole, lysosome, Golgi bodies, endoplasmic reticulum), we need to identify which organelle can exist in more than one shape.

3. **Analyzing Each Option**:
- **Vacuole**: Generally, vacuoles have a consistent shape and do not exhibit polymorphism.
- **Lysosome**: Lysosomes can exist in several forms:
- **Primary Lysosomes**: Newly formed, containing inactive enzymes.
- **Secondary Lysosomes**: Formed when primary lysosomes fuse with phagosomes and contain active enzymes for digestion.
- **Residual Bodies**: Contain undigested material after digestion.
- **Autophagic Vacuoles**: Formed during the process of autophagy, where lysosomes engulf parts of the cell.
- **Golgi Bodies**: These maintain a consistent structure and do not exhibit polymorphism.
- **Endoplasmic Reticulum**: Similar to Golgi bodies, the endoplasmic reticulum maintains a stable structure.

4. **Conclusion**:
- Based on the analysis, the only organelle that exhibits polymorphism is the **lysosome**. Therefore, the correct answer is **lysosome**.

### Final Answer
The polymorphic cell organelle is **lysosome**.
