Who was the first person to propose the concept of photosynthesis?
PHOTOSYNTHESIS TIMELINES. Hugo von Mohl makes detailed observations of the structure of chloroplasts. Julius Robert von Mayer proposes that the sun is the ultimate source of energy utilized by living organisms, and introduces the concept that photosynthesis is a conversion of light energy into chemical energy.
What is the timeline of photosynthesis on Earth?
Timeline of Photosynthesis on Earth. Photosynthesis evolved early in Earth’s history. The rapidity of its emergence suggests it was no fluke and could arise on other worlds, too. As organisms released gases that changed the very lighting conditions on which they depended, they had to evolve new colors.
When did Engelmann discover the action spectrum of photosynthesis?
1883 Theodor Wilhelm Engelmann illuminates a filamentous alga with light dispersed through a prism. He finds that motile aerobic bacteria congregate near the portions illuminated by red and blue wavelengths, thus producing the first action spectrum for photosynthetic oxygen evolution.
When did the first photosynthetic bacteria appear on Earth?
4.6 billion years ago -- Formation of Earth. 3.4 billion years ago -- First photosynthetic bacteria. They absorbed near-infrared rather than visible light and produced sulfur or sulfate compounds rather than oxygen.
