- The cell theory was proposed by scientists Matthias Schleiden and Theodor Schwann in the 19th century.
- The cell theory states that all living things are composed of cells, and cells are the basic units of life.
Unicellular vs. Multicellular Organisms

- Multicellular organisms are made up of many cells that work together, allowing for division of labor and specialization of functions.
