Definition
Cell theory is a fundamental principle in biology stating 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 through division.
Summary
Cell theory is a cornerstone of biology that explains the fundamental role of cells in all living organisms. It emphasizes that all life forms are composed of cells, which are the basic units of life, and that new cells arise from existing ones. This theory has been pivotal in advancing our understanding of biology, medicine, and genetics. The development of cell theory involved key contributions from scientists like Schleiden, Schwann, and Virchow. Their work has led to significant advancements in various fields, including medical research and biotechnology, highlighting the importance of cells in health and disease. Understanding cell theory is essential for anyone studying biology, as it lays the groundwork for more complex concepts in life sciences.
