Explanation:
Detailed explanation-1: -The first is that all living things are made up of at least one cell. The second is that the cell is the basic unit of life. And the third principle of cell theory is that all cells come from preexisting cells.
Detailed explanation-2: -Major contributors to cell theory are Robert Hooke, Antonie van Leeuwenhoek, Matthias Schleiden, Theodor Schwann, and Rudolf Virchow.
Detailed explanation-3: -Three critical discoveries made during the 1830s, when improved microscopes with suitable lenses, higher powers of magnification without aberration, and more satisfactory illumination became available, were decisive events in the early development of cell theory.
