Which of the following organelle (s) is/are not include in endomembrane system

Options

A. Endoplasmic Reticulum
B. Golgibody
C. Lysosomers and vacuoles
D. Mitochondria, chloroplast and ribosome

Answer

To determine which organelles are not included in the endomembrane system, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Endomembrane System**: The endomembrane system consists of a group of membrane-bound organelles that work together in the synthesis, modification, packaging, and transport of proteins and lipids.

2. **Identify the Organelles in the Endomembrane System**: The key organelles that are part of the endomembrane system include:
- Endoplasmic Reticulum (ER)
- Golgi Apparatus (Golgi Body)
- Lysosomes
- Vacuoles

3. **Identify the Organelles Not in the Endomembrane System**: The organelles that are not part of the endomembrane system include:
- Mitochondria
- Chloroplasts
- Ribosomes

4. **Select the Correct Answer**: From the list provided, the organelles that are not included in the endomembrane system are:
- Mitochondria
- Chloroplasts
- Ribosomes

### Conclusion:
Thus, the correct answer to the question is that the organelles not included in the endomembrane system are **mitochondria, chloroplasts, and ribosomes**.
