Q.Name any two nutrient media that you have studied.

MS medium and White's medium are two examples of the nutrient media used to grow plant tissue cultures.

Working

In plant tissue culture, the nutrient (culture) medium supplies the explant with all the nutrients it needs to grow and differentiate outside the parent plant -- macronutrients, micronutrients, a carbon source (usually sucrose), vitamins, amino acids, plant growth regulators (auxins/cytokinins), and, for a solid medium, a gelling agent such as agar. Several standard formulations have been developed for different purposes:

1. MS medium (Murashige and Skoog medium, 1962): the most widely and commonly used tissue-culture medium across a very large range of plant species, characterised by a relatively high concentration of mineral salts (especially nitrate and ammonium), which supports vigorous growth for callus induction, organogenesis, and micropropagation. …
