The production of plants by cells or tissues or organs in a synthetic medium is called tissue culture. This technique is also Know as micro propagation technique. The synthetic medium used in this technique contains all the nutrients and hormones which are required for the growth.

A cell or tissue is transferred into suitable synthetic medium under sterile conditions.

The tissue often develops into a fast growing cellular mass called callus. The callus is transferred to another medium for growth and differentiation that forms plantlets. The plantlets can be transplanted into soil or pots where they can be grown to maturity.

Tissue culture technique is being popularly used for production of ornamental plants like Orchids, Dahlia and Carnation.
