Select the correct option of organelle with its function.

Options

A. Golgi apparatus - packaging and transportation of proteins
B. Lysosomes- excretion in some organisms like Amoeba
C. RER- synthesis and breakdown of lipids
D. Cilia - hair-like appendage which plays a role in bacterial conjugation

Answer

To solve the question "Select the correct option of organelle with its function," we will analyze each option provided and determine which one correctly matches an organelle with its function.

### Step-by-Step Solution:

1. **Option Analysis**:
- **Option 1**: Golgi apparatus - involved in the packaging and transportation of proteins.
- **Explanation**: The Golgi apparatus receives proteins from the endoplasmic reticulum, modifies them, sorts them, and then packages them for transport. This function is accurate.

2. **Evaluate Other Options**:
- **Option 2**: Lysosomes - excretion in some organisms like amoeba.
- **Explanation**: This statement is incorrect. In amoeba, the contractile vacuole is responsible for excretion, not lysosomes.

- **Option 3**: Smooth endoplasmic reticulum - synthesizes and breaks down lipids.
- **Explanation**: While the smooth endoplasmic reticulum does synthesize lipids, the statement is misleading as it implies that it also breaks down lipids, which is not its primary function.

- **Option 4**: Cilia - hair-like appendage involved in bacterial conjugation.
- **Explanation**: This statement is incorrect because the hair-like appendages involved in bacterial conjugation are called pili, not cilia.

3. **Conclusion**:
- The only correct option is **Option 1**: Golgi apparatus - involved in the packaging and transportation of proteins.

### Final Answer:
**Correct Option: Golgi apparatus - involved in the packaging and transportation of proteins.**
