Cell History (old version)
Beverly Biology・2 minutes read
The cell theory, established by scientists like Robert Hook, Matthias Schleiden, Theodor Schwann, and Rudolf Virchow, proposes that all life is composed of cells that come from other cells through multiplication. While the origin of the first cell remains a mystery, the evolution of cells from prokaryotes to eukaryotes, supported by the endosymbiosis theory, highlights the interconnectedness and complexity of cellular life.
Insights
- Robert Hook discovered cells in the 1600s using a microscope, observing cork cells.
- The cell theory, developed by Matthias Schleiden, Theodor Schwann, and Rudolf Virchow, states that all life is composed of cells, with cells multiplying and coming from other cells.
