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. WebChloroplasts are like tiny green factories within plant cells that help convert energy from sunlight into sugars, and they have many similarities to mitochondria. The evidence suggests that these chloroplast organelles were also once free-living bacteria.

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… Web9 de jan. de 2024 · In fact, the DNA in the chloroplast is very similar to photosynthetic bacteria called cyanobacteria. The DNA in the mitochondria is most like that of the bacteria that causes typhus. Before these prokaryotes were able to undergo endosymbiosis, they first most likely had to become colonial organisms.
