  Washington (UPI) Jul 25, 2019 Scientists have discovered unusual structures in rare bacteria that resemble the cellular components that power photosynthesis. The discovery, described this week in the journal Trends in Plant Science, suggests photosynthesis has ancient evolutionary roots. Plants, algae and some bacteria perform what's known as oxygenic photosynthesis, splitting water into oxygen and hydrogen to power the process that turns solar energy into food. Some bacteria use anoxygenic photosynthesis, splitting other m ... read more |
