The endomembrane cell organelle with distinct cis and trans faces is

Options

A. Endoplasmic reticulum
B. Vacuole
C. Golgi complex
D. Lysosome

Answer

To answer the question "The endomembrane cell organelle with distinct cis and trans faces is," we will analyze the options provided and identify the correct organelle step by step.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for an endomembrane organelle that has distinct cis and trans faces.

2. **Review the Options**: The options given are:
- Endoplasmic Reticulum
- Vacuole
- Golgi Complex
- Lysosome

3. **Analyze Each Option**:
- **Endoplasmic Reticulum (ER)**: The ER is of two types - Smooth ER and Rough ER. The Smooth ER is involved in lipid synthesis, while the Rough ER is involved in protein synthesis due to the presence of ribosomes. However, the ER does not have distinct cis and trans faces.

- **Vacuole**: Vacuoles are membrane-bound spaces in the cytoplasm that store substances like water, nutrients, and waste products. They do not have distinct cis and trans faces.

- **Golgi Complex**: The Golgi apparatus, also known as the Golgi complex, is known for its distinct cis and trans faces. The cis face is the receiving side, where materials enter, and the trans face is the shipping side, where materials exit. This organelle is responsible for modifying, sorting, and packaging proteins and lipids.

- **Lysosome**: Lysosomes are vesicular structures that contain hydrolytic enzymes for digestion. They do not have distinct cis and trans faces.

4. **Conclusion**: Based on the analysis, the only organelle with distinct cis and trans faces is the **Golgi Complex**.

### Final Answer:
The endomembrane cell organelle with distinct cis and trans faces is the **Golgi Complex**.
