Answer:
Tissue culture is a method of artificial propogation of plants. It can be used to save a species of a plant. It can also be used if a plant is 90% damaged. We take a part of plant and put it in nutritive medium in a closed chamber under controlled condition. After a few days a group of cells called callus will grow
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 its application in the propagation of ornamental plants, or for growth of plants from a single parent, in disease-free condition.
