Robert Hooke observed from the microscope were not really cells at all, these are boxlike compartments that were formed because of empty cell walls of a dead plant tissue, which is cork. Hooke’s observation were limited because of the magnification power of his microscope, he would not know that these cells are dead because he did not understand that they could be alive. He preferred to concentrate on the prominent cell walls of the dead cork that he had first encountered.
Anton Van Leeuwenhoek (1674)
Anton Van Leeuwenhoek is a Dutch textile merchant produced small lenses that could magnify objects to almost 300 times their size. Using these superior lenses, he became the first to observe living cells including blood cells, sperm cells, bacteria and single-celled organisms like algae and protozoa that could be found in pond water. He reported his observations to the Royal Society of London in a series of letters during late 1600s. His detailed reports attest to both the high quality of its lenses and his keen powers of observation. He called the tiny organisms as “animalcules” meaning little animals
robert brown (1831)
Robert Brown found that every plant cell he looked at contained a rounded structure, which he called a “nucleus. A term derived from the Latin word for “kernel”
Matthias Schleiden (1838)
After describing and observing the cells, Matthias Schleiden, a botanists, made a careful study about plant tissues to recognize the importance of cells.He stated that all plants “are aggregates of fully individualized, independent, separate beings, namely the cells themselves.”

1. Cells arise only by division of a previously existing cell. Although life likely evolved spontaneously in the environment of the early earth, biologists have concluded that no additional cells are originating spontaneously at present. Rather, life on earth represents a continuous line of descent from those early cells
