The integration of biological processes and engineering has long been recognized as being capable of creating effects beneficial to human kind.
Plants play a very important role in the natural environment and human life.
Plants require proper environments to grow and develop. In return, plants contribute to the regeneration of the environment. The study of plant based engineering systems originated from a need to produce plants of high quality during the time when the natural environment is not conducive to plant growth. The purpose of plant production has been mostly for satisfying market needs. Recently, plants have taken on extra roles within a plant based engineering system.
