Tissue culture is a technique of growing new plants from cells or tissue from the growing tip of already existing plant, in an artificial medium. The process of tissue culture is as follows:

1. Cells or tissue from the growing tip of a plant are removed or separated.

2. These cells are placed in an artificial medium, where they divide to form a group of cells called callus.

3. The callus is then transferred to a medium, which has hormones for growth and differentiation.

4. This results in growth of small plantlets, which are then placed in the soil to grow into mature plants.

This technique is finding it’s application in the propagation of ornamental plants, or for growth of plants from a single parent, in disease-free condition.
