After packing materials Golgi apparatus secretes then to the

Options

A. inside of the cell
B. outside of the cell
C. both of them
D. secretion is not a function of Golgi

Answer

### Step-by-Step Solution:

1. **Understanding the Golgi Apparatus**: The Golgi apparatus is an essential organelle in the cell responsible for modifying, sorting, and packaging proteins and lipids that have been synthesized in the endoplasmic reticulum (ER).

2. **Function of the Golgi Apparatus**: After receiving materials from the ER, the Golgi apparatus processes these materials. This includes sorting, modifying, and packaging them into vesicles.

3. **Secretion Pathways**: The vesicles that bud off from the Golgi apparatus can take two main pathways:
- **Towards the Plasma Membrane**: Some vesicles will move towards the plasma membrane to secrete their contents outside the cell. This is crucial for the release of hormones, neurotransmitters, and other signaling molecules.
- **Towards Lysosomes**: Other vesicles may contain enzymes and materials that will be sent to lysosomes, which are involved in digestion and waste removal within the cell.

4. **Analyzing the Options**:
- **Option 1**: "Inside of the cell" - This is correct as some vesicles go to lysosomes.
- **Option 2**: "Outside of the cell" - This is also correct as some vesicles fuse with the plasma membrane to secrete materials outside.
- **Option 3**: "Both of them" - This option is correct because it encompasses both pathways.
- **Option 4**: "Secretion is not the function of the Golgi" - This is incorrect since secretion is indeed one of the primary functions of the Golgi apparatus.

5. **Conclusion**: The correct answer is option 3, as the Golgi apparatus secretes materials both inside the cell (to lysosomes) and outside the cell (to the plasma membrane).
