The simulated growth of plants is a significant task in of systems biology and mathematical biology, which seeks to reproduce plant morphology with computer software.Electronic trees (e-trees) usually use L-systems to simulate growth. L-systems are very important in the field of complexity science and A-life.A universally accepted system for describing changes in plant morphology at the cellular or modular level has yet to be devised.The most widely implemented tree-generating algorithms are described in the papers "Creation and Rendering of Realistic Trees", and Real-Time Tree Rendering
