Endoplasmic reticulum
In this Class 9 Science topic from “Cell: The Building Block of Life,” students learn how the endoplasmic reticulum (ER) forms a membrane-bound network inside the cell. They explore the structure and functions of rough ER, which bears ribosomes and helps make and transport proteins, and smooth ER, which supports lipid synthesis and detoxification. The topic also explains how the ER contributes to the internal transport and organisation of cell activities.
