Solution: Tissue culture, we know, has made it feasible to grow a new plant from any portion of an existing one. Tissue culture is the method through which we can produce thousands of plants of the same type by a single cell. The growth takes place under sterile conditions in a special nutrient medium that contains a carbon source, inorganic salts, amino acids, vitamins, and other growth regulators.

An explant is a small piece of a plant that is used to grow a plant through tissue culture. As a result, a single plant cell can theoretically be used to create a thousand plants of the same species.
