Detailed explanation-1: -Plant tissue culture media should generally contain some or all of the following components: macronutrients, micronutrients, vitamins, amino acids or nitrogen supplements, source(s) of carbon, undefined organic supplements, growth regulators and solidifying agents.

Detailed explanation-2: -Plant tissue and cell culture media are generally made up of some or all of the following components: macronutrients, micronutrients, vitamins, amino acids or other nitrogen supplements, sugar(s), other undefined organic supplements, solidifying agents or support systems, and growth regulators.

Detailed explanation-3: -Essential components of cell culture media include carbohydrates, amino acids, vitamins, minerals, and a pH buffer system. Your choice of media can affect the accuracy, reproducibility, and relevance of your experimental results.

Detailed explanation-4: -In the present study glycine surpassed all other amino acids in somatic embryoge-nesis and regeneration of shoots from sugarcane callus. It can be explained by its role as a source of organic nitrogen as well as its use in restructuring of dividing cells through synthesis of cell wall.
