In 1838, a German botanist, Matthias Schleiden suggested that cells were the basic structural unit of all plant matter. German zoologist, Theodor Schwann proposed that animals were made up of cells.

In1862, French biologist, Louis Pasteur carried out an experiment that disproved the old idea of spontaneous generation. His experiment involved swan-necked flasks, open to air.

Hence supporting the view that cells are produced from pre-existing cells.
