The cell organelle which principally performs the function of packaging materials in a cell is

Options

A. RER
B. SER
C. Golgi complex
D. Cell wall

Answer

To answer the question, "The cell organelle which principally performs the function of packaging materials in a cell is," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Options**: The options given are RER (Rough Endoplasmic Reticulum), SER (Smooth Endoplasmic Reticulum), Golgi complexes, and the cell wall.

2. **Analyze Each Option**:
- **Cell Wall**: The cell wall is primarily responsible for protecting the cell and maintaining its shape. It does not play a role in packaging materials. Therefore, this option is incorrect.
- **Rough Endoplasmic Reticulum (RER)**: The RER is involved in protein synthesis due to the presence of ribosomes on its surface. While it plays a role in the secretion of proteins, it is not primarily responsible for packaging. Hence, this option is also incorrect.
- **Smooth Endoplasmic Reticulum (SER)**: The SER is involved in lipid synthesis and does not have ribosomes. Similar to the RER, it is not responsible for packaging materials. Thus, this option is incorrect as well.
- **Golgi Complexes**: The Golgi apparatus (or Golgi complexes) is known for its role in modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles. This makes it the principal organelle for packaging materials in the cell.

3. **Conclusion**: Based on the analysis, the correct answer is **Golgi complexes**.

### Final Answer:
The cell organelle which principally performs the function of packaging materials in a cell is **Golgi complexes**.
