Cell theory
In Class 9 Science, the topic Cell Theory introduces the central ideas that explain why the cell is called the building block of life. Students learn that all living organisms are made of one or more cells, the cell is the basic structural and functional unit of life, and new cells arise from pre-existing cells. The topic also connects the contributions of Schleiden, Schwann and Virchow with the development of modern cell biology and helps learners understand how cells form the foundation of tissues and organisms.
