in 1838 schleiden a German botanist concluded that ,despite differences in the structure of various tissues ,plants were made up of cells .in 1839 a German zoologist T.Schwann published a comprehensive report on the cellular basis of animals.both of them proposed the cell theory which states that:
all organisms are composed of one or more cells
the cell is the structural and functional unit of life
cells can arise only by division of pre existing cell.
RUDOLF VIRCHOW VIEW
schleiden and schwann idea on the origin of cell was not convincing ,both agreed that cell is a denvo structure, could arise from non cellular material .in 1855 RUDOLF VIRCHOW a German pathologist, had made a convincing case and added a third point to the cell theory and is that
#cells can arise only by division of pre existing cell. it is not a denovo structure.
