Cell membrane and cell wall
In Class 9 Science, this topic explains how the cell membrane and cell wall protect cells and control their interaction with the surroundings. Students learn that the selectively permeable cell membrane regulates the movement of substances, while the rigid cell wall provides shape, strength, and protection in plant cells. It also clarifies the differences between plant and animal cells and connects membrane transport with basic ideas such as diffusion and osmosis, within the chapter Cell: The Building Block of Life.
