With the exception of a very few species of angiosperms (e.g., obligate parasites and mycoheterotrophs), both groups rely on photosynthesis for energy. Angiosperms represent approximately 80 percent of all known living green plants. Various organisms solved these problems in different ways, resulting in physical differences between tissues and chemical alterations that increased the genetic variation of plant species. The earliest reliable record of gymnosperms dates their appearance to the Carboniferous period (359-299 million years ago).
