Hint: Cellular totipotency is the ability of a somatic cell / explant to produce a complete organism.

Complete Answer:
- Somatic all / explant produce a complete organism by totipotency
- The explants are treated with specific anti – microbial chemicals to make them free from microbes.
- Culture media containing inorg –
- Anti balts, certain vitamins, sucrose (as a source of carbon and energy) and the desired growth regulators are provided, required for desired growth and development of the explant.
- Totipotency comes under tissue culture.
- Tissue culture is the technique of maintaining and growing plant cells, tissues or organs aseptically on artificial medium in suitable containers under conditions in vitro. The part which is cultured is called sicplant.

The correct option is (D) complete now organism.

Note: The concept of cellular totipotency in plants was given by – Haberlandt.
- Nutrient media must provide carbon sources such as sucrose inorganic salts, vitamins, amino acids and growth regulators like aumin, cytokinins etc.
- Method of propagation / producing thousands of plants through tissue culture is called micro – propagation.
- Plants like tomato, banana, apple etc. are produced by tissue culture method by using explants (which have the capacity to generate a whole plant i.e. totipotency.
