What is tissue culture? Write in brief.

Plant tissue culture is based on the property of the plant cells to regenerate a whole plant, that is totipotency.

Tissue culture is the process of propagating new plants from a small piece of a plant's tissue, obtained from the growing tip of that plant in a suitable growth medium.

Tissue culture for asexual reproduction is initiated by selecting single cells, plants cells without cell walls (protoplasts), pieces of leaves, or small parts of stems or roots and placed in the culture media with nutrients and plant hormones.

Orchids, Dahlia, Carnation and Chrysanthemum are propagated by the method of tissue culture.
