Besides producing secretory vesicles, the function of golgibody is:-

Options

A. Lysosome formation
B. Formation of spindle fibers
C. Formation of E.R.
D. All the above

Answer

### Step-by-Step Solution:

1. **Understanding the Golgi Body**: The Golgi body, also known as the Golgi apparatus, is an essential organelle in eukaryotic cells. Its primary function is to modify, sort, and package proteins and lipids that have been synthesized in the endoplasmic reticulum (ER).

2. **Secretory Vesicles Production**: The question states that we should consider functions of the Golgi body besides producing secretory vesicles. The Golgi apparatus is indeed involved in the formation of secretory vesicles, which transport proteins and lipids to various destinations, including the plasma membrane for secretion.

3. **Formation of Lysosomes**: One of the critical functions of the Golgi body, aside from producing secretory vesicles, is the formation of lysosomes. Lysosomes are membrane-bound organelles that contain hydrolytic enzymes responsible for breaking down waste materials and cellular debris. The Golgi apparatus packages these enzymes into lysosomes.

4. **Evaluating Other Options**:
- **Spindle Fiber Formation**: This function is incorrect as spindle fibers are formed during cell division, primarily involving centrioles, not the Golgi body.
- **Formation of Endoplasmic Reticulum**: This is also incorrect because the endoplasmic reticulum is a separate organelle and is not formed by the Golgi body.
- **All of the Above**: Since the previous options are incorrect, this option is also incorrect.

5. **Conclusion**: The correct answer to the question is that besides producing secretory vesicles, the Golgi body is primarily involved in the formation of lysosomes.

### Final Answer:
The function of the Golgi body, besides producing secretory vesicles, is the formation of lysosomes.
