Which cell organelle is formed in Golgi apparatus by the process of packaging?

Answer

### Step-by-Step Solution:

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

2. **Formation of Lysosomes**: One of the key functions of the Golgi apparatus is the formation of lysosomes. Lysosomes are membrane-bound organelles that contain hydrolytic enzymes.

3. **Role of Hydrolytic Enzymes**: These enzymes are responsible for breaking down biological molecules, which is why lysosomes are often referred to as "suicidal bags" of the cell. They play a vital role in cellular digestion and waste removal.

4. **Synthesis of Enzymes**: The hydrolytic enzymes found in lysosomes are initially synthesized in the endoplasmic reticulum (ER).

5. **Transport to Golgi Apparatus**: After synthesis, these precursor enzymes are transported to the Golgi apparatus, where they undergo further modifications.

6. **Activation and Packaging**: Within the Golgi apparatus, the enzymes become active and are packaged into vesicles, which then form lysosomes.

7. **Conclusion**: Therefore, the cell organelle that is formed in the Golgi apparatus by the process of packaging is the lysosome.

### Final Answer:
The cell organelle formed in the Golgi apparatus by the process of packaging is the **lysosome**.
