The fundamental concept behind tissue culture. It is the genetic potential of a plant cell to differentiate and develop into a complete, mature plant.
The "plantlets" are gradually introduced to the natural environment (soil and greenhouse) to build resilience against moisture loss and pathogens. Essential Components of the Culture Medium
– The culture of unorganized, undifferentiated cell masses on solid medium. Callus can be compact (densely packed cells) or friable (loosely packed, easily separated), and is induced by auxins such as 2,4-D.
The key distinction to understand is between (the complete destruction of all living microorganisms) and disinfection (the reduction of microbial populations). Four principal methods are employed: wet-heat sterilization (autoclaving at 121°C), dry-heat sterilization (oven heating at 140–160°C), filter sterilization (using membranes of 0.22–0.45 µm porosity for heat-sensitive compounds), and chemical sterilization (using agents such as ethanol or sodium hypochlorite).

Elongated shoots generated during Stage II are transferred to a rooting medium. This medium typically features reduced salt concentrations (e.g., half-strength MS medium), low or no cytokinins, and an increased level of auxins (like IBA or NAA) to stimulate adventitious root development. Stage IV: Acclimatization (Hardening)

Types of Culture (Briefly list Callus, Meristem, and Protoplast with real-world examples).
Any piece of plant tissue (e.g., leaf, stem, root, anther) excised from a donor plant and used to initiate a culture.
Plants grown in vitro live in a humid, sterile environment with low light. They lack a thick waxy cuticle and functional stomata. During hardening, plantlets are gradually introduced to greenhouse conditions with lower humidity and higher light intensity to build up their natural defenses before field transplantation.
