The endomembrane cell organelle formed by the packing acitvity of another endomembrane cell organelle is

Options

A. Ribosomes
B. Vacuoles
C. Lysosomes
D. all of them

Answer

To solve the question regarding which endomembrane cell organelle is formed by the packing activity of another endomembrane cell organelle, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for an endomembrane organelle that is formed by the packing activity of another endomembrane organelle.

2. **Identify Endomembrane Organelles**: The main endomembrane organelles include the endoplasmic reticulum (ER), Golgi apparatus, lysosomes, vacuoles, and vesicles.

3. **Focus on the Golgi Apparatus**: The Golgi apparatus is known for its role in modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.

4. **Recognize the Role of Lysosomes**: Lysosomes are specialized vesicles that contain digestive enzymes. They are formed from the Golgi apparatus and play a crucial role in breaking down waste materials and cellular debris.

5. **Determine the Correct Answer**: Since lysosomes are formed by the packing activity of the Golgi apparatus, the correct answer to the question is **lysosomes**.

6. **Evaluate Other Options**:
- **Ribosomes**: Not endomembrane organelles; they are involved in protein synthesis.
- **Vacuoles**: Primarily for storage, not directly formed from the Golgi.
- **Lysosomes**: Correct option as they are formed from the Golgi apparatus.

### Final Answer:
The endomembrane cell organelle formed by the packing activity of another endomembrane cell organelle is **lysosomes**.
