Technology such as lenses, magnifying glasses, and microscopes had an impact on the development of the cell theory. Below are some examples of how such technologies contributed to the cell theory.
- Robert Hooke is accredited with observing the first cells in 1665. At that time, Robert Hooke used a microscope to look at cork cells.
- In 1670, Antoni van Leeuwenhoek was accredited with being the first scientist to discover pond life. He used lenses to make the discovery.
- Robert Brown (1773-1858) used a microscope to discover the nucleus.
- More recently, the development of light and electron microscopes have enabled scientists to view living cells and molecules within cells respectively.
The cell theory is a scientific theory that describes the basic properties of cells. The cell theory states that cells are the smallest unit of life, that cells can only come from other living cells, and that all living things are made of cells.
