Plant cell culture is a technique for culturing plant cells under strictly controlled environmental conditions. Since plant cells are considered to be potentially totipotent, they have the potential to express the full range of genetic machinery encoded in the cell and, therefore, are capable of producing a full spectrum of Secondary metabolites.

Plant cell cultures can be independently propagated in climate- and soil-independent conditions by using large-capacity bioreactors. In addition, plant cells cultured in vitro are characterized by rapid growth and can accumulate a large amount of uniform biomass in a short period of time. This is a very important advantage, especially for the production of rare and endangered plants and rare biologically active compounds, which help to protect biodiversity
