Robert Hooke was the first to identify and name the cell in 1665. He noted that it looked oddly like the cells or tiny chambers that monks lived in, thus the name. Hooke, on the other hand, saw the dead cell walls of plant cells (cork) under the microscope. Life is all around us and we can find cells in all the organisms.
