WebThe smallest free-living cells include the pleuropneumonia -like organisms (PPLOs). Whereas an amoeba has a mass of 5 × 10 −7 gram (2 × 10 −8 ounce), a PPLO, which cannot be seen without a high-powered electron microscope, weighs 5 × 10 −16 gram (2 × 10 −15 ounce) and is only about 100 nanometres across. PPLOs grow very slowly. WebSep 4, 2024 · Discovery of Cells. The first time the word cell was used to refer to these tiny units of life was in 1665 by a British scientist named Robert Hooke. Hooke was one of the earliest scientists to study living things under a microscope. The microscopes of his day were not very strong, but Hooke was still able to make an important discovery.
