Which is not a function of Golgi body

Options

A. Secretion
B. Formation of plasma membrane
C. Fat synthesis
D. Cell wall formation

Explanation

To answer the question "Which is not a function of Golgi body?", we will analyze the functions of the Golgi body and identify the correct option that does not belong to its functions.

### Step-by-Step Solution:

1. **Understanding the Golgi Body**: The Golgi body, also known as the Golgi apparatus or Golgi complex, is a vital organelle in the cell responsible for modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.

2. **Identifying Functions of the Golgi Body**:
- **Secretion**: The Golgi body is involved in the secretion of substances. It processes and packages proteins that are to be secreted from the cell.
- **Formation of Plasma Membrane**: The Golgi apparatus plays a role in the formation and maintenance of the plasma membrane by processing and distributing membrane proteins and lipids.
- **Cell Wall Formation**: In plant cells, the Golgi body is involved in synthesizing components that contribute to the formation of the cell wall.

3. **Identifying the Incorrect Function**:
- **Fat Synthesis**: This function is primarily associated with the Smooth Endoplasmic Reticulum (SER), not the Golgi body. The SER is responsible for the synthesis of lipids, including fats.

4. **Conclusion**: Based on the analysis, the function that is **not** associated with the Golgi body is **fat synthesis**.

### Final Answer:
The function that is not a function of the Golgi body is **fat synthesis**.
