🧬 Endoplasmic Reticulum (ER) Explained | RER vs SER | Cell Biology Concept

The Endoplasmic Reticulum (ER) is one of the most fascinating organelles in eukaryotic cells! 🌿
It forms a large network of tubules and cisternae connected to the nucleus and Golgi apparatus, playing key roles in:
✨ Protein synthesis
✨ Lipid metabolism
✨ Calcium storage

In this video, you’ll learn:
🔹 What is Endoplasmic Reticulum (ER)?
🔹 Difference between Rough ER (RER) and Smooth ER (SER)
🔹 Why lipids are synthesized in SER, not cytoplasm
🔹 How proteins made on RER are transported to Golgi and beyond

Perfect for students of Class 11 Biology, or anyone curious about how our cells work!

📚 Topics Covered:

Structure of ER

Role of RER in protein synthesis

Function of SER in lipid metabolism

Protein and lipid trafficking in cells
