Packing of substances for export from the cell occurs in the

Options

A. SER
B. Golgi bodies
C. lysosome
D. nucleolus.

Answer

To answer the question "Packing of substances for export from the cell occurs in the," we will analyze the options provided and identify the correct organelle responsible for this function.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks where the packing of substances for export from the cell occurs. This implies we are looking for an organelle that is involved in the processing and packaging of materials that will leave the cell.

2. **Evaluate the Options**:
- **Smooth Endoplasmic Reticulum (SER)**: The SER is primarily involved in the synthesis of lipids and does not play a significant role in packaging substances for export.
- **Golgi Bodies (Golgi Apparatus)**: The Golgi apparatus is known for modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles. This is a key function of the Golgi bodies.
- **Lysosomes**: Lysosomes are involved in digestion and waste removal within the cell. They contain enzymes that break down cellular waste and are not involved in packaging substances for export.
- **Nucleolus**: The nucleolus is responsible for the assembly of ribosomes and does not participate in the packaging of substances for export.

3. **Identify the Correct Answer**: Based on the functions of the organelles evaluated, the Golgi bodies are responsible for the modification and packaging of substances for export from the cell.

4. **Conclusion**: Therefore, the correct answer to the question is **Golgi bodies**.

### Final Answer:
Packing of substances for export from the cell occurs in the **Golgi bodies**.
