All plants have a chemical in their leaves called chlorophyll. The chlorophyll is what makes the leaves of the plant green. But that is not the only job chlorophyll has. Its other job is to soak up the warmth and energy from the sun’s rays. Sun-energy isn’t all a plant needs to make its food, though. They also need water and air.
Without the sugar and light, the kernels would have died within a day. A plant that receives the nutrition it needs
will continue to live, we now know.
But what if we took all its O2 away?
Do you think that the plant could still grow? or The answer is actually "no, a plant could not grow without oxygen." Perhaps you're thinking that a plant needs to take in carbon dioxide in order to survive and that it expels oxygen as the waste product of photosynthesis.

their best glimpse yet into the origins of photosynthesis, one of nature’s most momentous innovations. By taking near-atomic, high-resolution X-ray images of proteins from primitive bacteria, investigators at Arizona State University and Pennsylvania State University have extrapolated what the earliest version of photosynthesis might have looked like nearly 3.5 billion years ago. If they are right, their findings could rewrite the evolutionary history of the process that life uses to convert sunlight into chemical energy.
Read in another language; Photosynthesis
Meanwhile, Redding and his team have just begun artificially converting the symmetric reaction center of heliobacteria into an asymmetrical one, following in the footsteps of two researchers in Japan, Hirozo Oh-Oka of Osaka University and Chihiro Azai of Ritsumeikan University, who have spent more than a decade doing this in another type of photosynthetic bacterium. The groups believe their work will clarify how these adaptations would have occurred in real life in the distant past.
The Balanced Chemical Equation for Photosynthesis?
That hypothesis contradicts one of the widely held ideas about the origins of photosynthesis: that species incapable of photosynthesis suddenly obtained the capacity through genes passed laterally from other organisms. According to Cardona, in light of the new discoveries, horizontal gene transfer and gene loss may both have played a role in the diversification of reaction centers, although he suspects that the latter may have been responsible for the earliest events. The finding, he said, might suggest that “the balance skews toward the gene-loss hypothesis”—and toward the idea that photosynthesis was an ancestral characteristic that some groups of bacteria lost over time.
Photosynthesis in Leaves That Aren't Green - Bay Nature
Cardona, who was not involved in the recent study but has begun interpreting its results, thinks he may have found a hint in the heliobacterium reaction center. According to him, the complex seems to have structural elements that would have later lent themselves to the production of oxygen during photosynthesis, even if that wasn’t their initial purpose. He found that a particular binding site for calcium in the heliobacteria’s structure was identical to the position of the manganese cluster in photosystem II, which made it possible to oxidize water and produce oxygen.
NitrogenOxygenCarbon isn't essential for photosynthesis.
1. Photosynthesis is the most important chemical process in the world. Without it, plants and people could not exist.
2. A plant’s leaves are vital for its survival. Most of the photosynthesis process takes place in the leaves of a plant.
