According to the growth characteristics of cells cultured in vitro whether they can be attached to scaffolds, they can be divided into attached growth and suspended growth. Adherent cells can adhere to the surface of branches and grow in culture. For example, amniotic fluid cells are adherent cells, which often show the growth of fibroblasts and epithelial cells. Suspended cells grow in suspension in culture medium.

Illumination: Plant cells cultured in vitro do not require high illumination conditions, because the substances needed for cell growth are mainly supplied by the culture medium. However, light is not only related to photosynthesis, but also to cell differentiation. For example, photoperiod can regulate sexual cell differentiation and flowering, so light conditions are particularly important in the early plant cell culture process for the purpose of obtaining plants. The process of obtaining important substances (such as drugs) by in vitro culture of plant cells, most of which are suspended in a reactor.
