The modern cell theory is the cornerstone of biology. It states that all living organisms are composed of one or more cells, the cell is the basic unit of life, and all cells arise from pre-existing cells. In a 9th-grade context, students must recognize the contributions of scientists like Schleiden, Schwann, and Virchow.
