Cell history and structure
The document outlines the historical development of cell theory, highlighting key figures like Zacharias Janssen, Robert Hooke, Anton van Leeuwenhoek, Matthias Schleiden, Theodore Schwann, and Rudolf Virchow. It describes the invention and use of the microscope, the discovery of cells, and the principles of cell theory, stating that all living things are composed of cells, which are the basic units of life that come from pre-existing cells. Additionally, it mentions essential cellular functions such as control, food acquisition, waste disposal, energy usage, transport, and reproduction.
