The cell theory was developed in the mid-19th century and is primarily attributed to three scientists: Matthias Schleiden, Theodor Schwann, and Rudolf Virchow.
1. **Matthias Schleiden** (1838) proposed that all plants are made of cells.
2. **Theodor Schwann** (1839) extended this idea to animals, stating that all living things are composed of cells.
3. **Rudolf Virchow** (1855) contributed the idea that all cells arise from pre-existing cells.
Together, their work laid the foundation for the modern understanding of cellular biology, encapsulated in the three main tenets of cell theory:
1. All living organisms are composed of one or more cells.
2. The cell is the basic unit of life.
3. All cells arise from pre-existing cells.
