Web9 de abr. de 2024 · Give some evidence supporting the theory that mitochondria and chloroplasts may have arisen from prokaryotic organisms. It is thought that life arose on earth around four billion years ago. The endosymbiotic theory states that some of the organelles in today's eukaryotic cells were once prokaryotic microbes. The evolution of photosynthesis refers to the origin and subsequent evolution of photosynthesis, the process by which light energy is used to assemble sugars from carbon dioxide and a hydrogen and electron source such as water. The process of photosynthesis was discovered by Jan Ingenhousz, a Dutch-born British physician and scientist, first publishing about it in 1779. The first photosynthetic organisms probably evolved early in the evolutionary history of life and m…

WebLiving things have evolved into three large clusters of closely related organisms, called "domains": Archaea, Bacteria, and Eukaryota.
