Technicians in a commercial biotechnology laboratory are using micropropagation to produce virus-free clones of the Cavendish banana (Musa acuminata) from shoot-tip meristem tissue.
Identify a suitable instrument used to slice the shoot-tip into explants, and describe two aseptic precautions taken during the transfer stage to prevent microbial contamination of the nutrient agar.
The agar growth medium contains essential inorganic ions and a carbon source. Name one specific mineral ion and one specific carbohydrate required by the explants, and explain their biological roles in facilitating growth.
State three environmental conditions within the incubation chamber that must be regulated to ensure the successful regeneration of the explants into plantlets.
