Question

Many plants such as orchids are grown by technique called tissue culture. Small pieces of plant tissue from a left, stem, or roots of a mature plants 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?

Answer 1

The cells initially have no specialization and over time time, their degree of specialization tends to increase.
In animals, stem cells are an example of undifferentiated cells.
