Detailed Solution

Step 1: Definition of Endomembrane System

The endomembrane system is a group of membranes and organelles in eukaryotic cells that work together to modify, package, and transport lipids and proteins. These organelles are functionally coordinated.

Step 2: Identifying Components

The components of the endomembrane system include the Endoplasmic Reticulum (ER), Golgi complex, Lysosomes, and Vacuoles.

Step 3: Evaluating Exclusions

Organelles like Mitochondria, Chloroplasts, and Peroxisomes are not considered part of the endomembrane system because their functions are not coordinated with the ER-Golgi-Lysosome-Vacuole pathway.

Step 4: Conclusion

Comparing the options, option (B) correctly lists the four components that constitute the endomembrane system.

Final Answer: endoplasmic reticulum, Golgi complex, lysosomes and vacuole
