Explanation:
Detailed explanation-1: -Examples of uses for these cultures include secondary metabolite production for drugs, flavorings and fragrances, and micropropagation, including the production of somatic embryos. In the latter case, highly efficient propagation can be achieved using cell suspension cultures.
Detailed explanation-2: -Characteristics and advantages of Suspension cell culture Large-scale suspension cultures are constantly agitated to allow for adequate gas and nutrient exchange. This is primarily achieved by the use of a magnetic stirrer or rotating spinner flasks.
