Explanation:
The cell theory states that all biological organisms are composed of cells; cells are the unit of life and all life come from preexisting life. The cell theory is so established today that it forms one of the unifying principles of biology.
The word cell was first used by Robert Hooke (1635–1703) when he looked at cork with a simple microscope and found what appeared to be b
locks of material making up the cork. The term today describes a microscopic unit of life that separates itself from its surroundings by a thin partition, the cell membrane.
Most biologists believe that life arose spontaneously from inanimate matter, but the details of how this could have happened remain unknown, and the time scale was long. Rudolf Virchow, a German pathologist (1821–1902), famously wrote “omnis cellula e cellula”—all cells come from other cells—meaning that spontaneous generation of living things from inanimate matter does not occur over periods as short as our lifetimes.
