The Cell Theory
The Cell Theory, a foundational principle in biology, revolutionized our understanding of life's fundamental unit. Developed in the 19th century, this theory postulates three essential concepts: all living organisms are composed of cells, the cell is the basic unit of life, and all cells arise from pre-existing cells. Pioneered by scientists such as Matthias Schleiden, Theodor Schwann, and Rudolf Virchow, the Cell Theory has become the cornerstone of modern biology, shaping our comprehension of the intricate structures and processes that govern living organisms.
