Cell Theory

Cell Theory is a cornerstone of biology, asserting that all living organisms are composed of cells, the cell is the basic unit of life, and all cells arise from pre-existing cells. These principles, expanded by modern discoveries, emphasize the fundamental role of cells in structure, function, and heredity, profoundly shaping our understanding of life.

Cell Theory Notes – Definition, Parts, History, & Examples

Cell Theory is a foundational biological principle stating that all living organisms are composed of cells, the cell is the basic unit of life, and all cells arise from pre-existing cells. Developed by scientists Schleiden, Schwann, and Virchow in the 19th century, this theory underscores the role of cells in the structure, function, and continuity of life.
