Explanation:
The scientific process by which cells, tissues or organs are developed in nutrient media to fulfil the demand, is called plant tissue culture.
The plant part taken out to be grown in a test-tube in special nutrient media is called explant. And the capacity of producing a whole plant from explant is called totipotency.
The nutrient media must provide a carbon source (such as sucrose), inorganic salts, vitamins, amino acids and growth regulators such as auxins, cytokinins, etc.
The production of a large number of plants in a short duration is practiced in floriculture and horticulture industry today, is known as micro-propagation. It is a technique of obtaining large number of plantlets by the tissue culture method.
The plants thus, generated are genetically similar to the original plant through which they are grown, so they are called somaclones. To recover healthy plants from diseased plants, meristem culture is practiced.
Meristem (axillary and apical) is the only virus-free part of virus-unaffected plant. Plants developed from meristem are banana, sugarcane, potato, etc.
