G. Haberlandt, a German botanist,
in 1902 cultured fully differentiated plant cells
isolated from different plants. This was the very
first step for the beginning of plant cell and
tissue culture. Further contributions were made
by the Cell Doctrine which admitted that a cell
is capable of showing totipotency.
