Many plants such as orchids are grown by a technique called tissue culture. Small pieces of plant tissue from a leaf, stem, or root of a mature plant are placed in a medium that contains the proper nutrients. The cells first form a mass of undifferentiated cells, from which tiny roots, stems, and leaves eventually grow. How do the plant cells placed in a medium for tissue culture change in terms of their degree of specialization? what types of animal cells are most similar to the undifferentiated plant cells in a tissue culture?
