Lysosome arises from which cell organelle ?

Options

A. Nucleus
B. Endoplasmic reticulum
C. Golgi Apparatus
D. Both 2 & 3

Answer

### Step-by-Step Solution:

1. **Understanding Lysosomes**: Lysosomes are membrane-bound organelles that contain digestive enzymes. They play a crucial role in breaking down waste materials and cellular debris.

2. **Identifying the Origin**: The question asks from which cell organelle lysosomes arise. The main organelles involved in the formation of lysosomes are the Golgi apparatus and the endoplasmic reticulum.

3. **Role of the Endoplasmic Reticulum (ER)**: The endoplasmic reticulum is responsible for the synthesis of proteins. These proteins are then transported to the Golgi apparatus for further processing.

4. **Role of the Golgi Apparatus**: The Golgi apparatus modifies, sorts, and packages proteins received from the endoplasmic reticulum. It is here that the proteins destined for lysosomes are marked and packaged into vesicles.

5. **Formation of Lysosomes**: The vesicles containing the proteins from the Golgi apparatus fuse with late endosomes, which then mature into lysosomes. This process is crucial for the proper functioning of lysosomes.

6. **Conclusion**: Therefore, lysosomes arise from the Golgi apparatus, and they also have a connection with the endoplasmic reticulum in terms of protein synthesis.

7. **Final Answer**: The correct answer to the question is that lysosomes arise from the Golgi apparatus, and they are also associated with the endoplasmic reticulum.
