What are the various components of the medium used for the in vitro propagation of explants?

(N/A) The major components of the culture medium used for the in vitro propagation of explants include:
$1$. Carbon sources: Primarily sucrose,which serves as an energy source.
$2$. Inorganic salts: Essential minerals required for plant growth.
$3$. Vitamins: Necessary for metabolic processes.
$4$. Amino acids: Sources of nitrogen for protein synthesis.
$5$. Water: The solvent for all nutrients.
$6$. Agar-agar: $A$ solidifying agent used to provide a firm support for the explants.
$7$. Growth hormones: Specific plant growth regulators such as auxins and cytokinins (or gibberellins) are added to induce differentiation and growth.
