It begins with the discovery of the cell by Robert Hooke and the development of the cell theory by Schleiden and Schwann, later expanded by Rudolf Virchow. The chapter clearly differentiates between prokaryotic and eukaryotic cells based on structure, size, and organization. It also describes the detailed structure and functions of important cell organelles such as the nucleus, mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles, plastids, and cytoskeleton. Special emphasis is given to how each organelle performs specific functions that help in maintaining life processes like respiration, protein synthesis, transport, and energy production. Overall, the chapter helps students understand how the coordinated functioning of various cell components makes life possible. for competitive exams like NEET and other entrance tests.
