zone of exclusion surrounds

Options

A. Golgi complex and centriole
B. Mitochondria and plastids
C. Nucleus and endoplasmic reticulum
D. Ribosome and lysosome

Answer

**Step-by-Step Solution:**

1. **Understanding the Zone of Exclusion**: The zone of exclusion is a cytoplasmic layer that surrounds certain organelles within the cell. Its primary function is to protect these organelles from mixing with other cellular components.

2. **Identifying the Organelles**: The question asks which organelles are surrounded by the zone of exclusion. The video transcript mentions that this zone is found around the Golgi complex and centrioles.

3. **Function of the Zone of Exclusion**: This layer plays a crucial role in antimicrobial activity, ensuring that external substances do not interfere with the organelles' functions. It helps maintain the integrity of the organelles involved in transporting food and other materials within the cell.

4. **Comparison with Other Organelles**: The transcript notes that other organelles, which possess a double membrane structure, do not require a zone of exclusion. This is because the double membrane provides sufficient protection against external influences.

5. **Conclusion**: Based on the information provided, the zone of exclusion surrounds the Golgi complex and centrioles. Therefore, the correct answer to the question is that the zone of exclusion surrounds these two organelles.

**Final Answer**: The zone of exclusion surrounds the Golgi complex and centrioles.
