On among the following is considered as a part of endomembrane system

Options

A. Vacuole
B. Peroxisome
C. Chloroplast
D. Mitochondria

Answer

To determine which of the following is considered a part of the endomembrane system, we need to analyze the options given: vacuole, peroxisome, chloroplast, and mitochondria.

### Step-by-Step Solution:

1. **Understand the Endomembrane System**: The endomembrane system is a group of membranes and organelles that work together to modify, package, and transport lipids and proteins. Key components include the endoplasmic reticulum, Golgi apparatus, lysosomes, and vacuoles.

2. **Analyze Each Option**:
- **Vacuole**: Vacuoles are storage organelles that are part of the endomembrane system. They help in storing nutrients, waste products, and other materials.
- **Peroxisome**: Peroxisomes are involved in metabolic processes, particularly the breakdown of fatty acids and detoxification. They are not part of the endomembrane system.
- **Chloroplast**: Chloroplasts are involved in photosynthesis and are not part of the endomembrane system.
- **Mitochondria**: Mitochondria are the powerhouses of the cell, generating ATP through respiration, and they are also not part of the endomembrane system.

3. **Identify the Correct Answer**: Among the options, only the vacuole is a part of the endomembrane system.

### Conclusion:
The correct answer is **vacuole** (Option A).
