Study Chapter Details
UP Board Class 11 Biology – Cell: The Unit of Life
The chapter “Cell: The Unit of Life” in UP Board Class 11 Biology introduces students to the basic structural and functional unit of all living organisms—the cell. It explains the cell theory, proposed by scientists like Schleiden, Schwann, and Virchow, which states that all living organisms are made of cells and that cells arise from pre-existing cells.
Students learn about prokaryotic and eukaryotic cells, differences in structure and function, and the organization of cell organelles like nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, ribosomes, and plastids. The chapter also covers cell membrane structure, transport mechanisms, and cell division (mitosis and meiosis), highlighting their significance in growth, reproduction, and inheritance.
Understanding the cell is fundamental for studying advanced topics in genetics, physiology, and molecular biology. This chapter provides the foundation for all biological studies and is crucial for competitive exams like NEET and CUET.
