Oxygenic photosynthesis uses water ..

Great question! Plants produce oxygen, becausewhen they photosynthesize, they take carbondioxide (CO2; a gas-form of carbonbonded to two oxygen molecules) and water(H2O; an oxygen bonded to two hydrogenatoms) and combine them using light energy toproduce sugars and oxygen. This stores the energyin chemical bonds (in the sugars) and releasesO2.The chemical equation for thisis:6CO2 + 6H2C6H12O6(sugar) +6O2

Photosynthesis works by absorbing light. Light energy causes the molecules in chlorophyll to lose electrons but they gain photons. This sets off a chain reaction that causes the plant to lose NADP and NADPH. The reduction causes the plant to produce ATP which then replaces the electrons that were previously lost through a process known as water photolysis. This process also causes a dioxide (O2) molecule to be released, which is what we know as oxygen. Not all forms of light are absorbed through this process, however, and the remaining wavelengths are what decides the color of the plant. For example, green plants do not absorb the equivalent wavelength so the plant appears to be green, while all other wavelengths are absorbed.

When sea levels rise as dramatically as they did in the Cretaceous, coral reefs will be buried under rising waters and the ideal position, for both photosynthesis and oxygenation, is lost, and reefs can die, like burying a tree’s roots. About 125 mya, reefs made by , which thrived on , began to displace reefs made by stony corals. They may have prevailed because they could tolerate hot and saline waters better than stony corals could. About 116 mya, an , probably caused by volcanism, which temporarily halted rudist domination. But rudists flourished until the late Cretaceous, when they went extinct, perhaps due to changing climate, although there is also evidence that the rudists . Carbon dioxide levels steadily fell from the early Cretaceous until today, temperatures fell during the Cretaceous, and hot-climate organisms gradually became extinct during the Cretaceous. Around 93 mya, , perhaps caused by underwater volcanism, which again seems to have largely been confined to marine biomes. It was much more devastating than the previous one, and rudists were hit hard, although it was a more regional event. That event seems to have , and a family of . On land, , some of which seem to have , also went extinct. There had been a decline in sauropod and ornithischian diversity before that 93 mya extinction, but it subsequently rebounded. In the oceans, biomes beyond 60 degrees latitude were barely impacted, while those closer to the equator were devastated, which suggests that oceanic cooling was related. shows rising oxygen and declining carbon dioxide in the late Cretaceous, which reflected a general cooling trend that began in the mid-Cretaceous. Among the numerous hypotheses posited, late Cretaceous climate changes have been invoked for slowly driving dinosaurs to extinction, in the “they went out with a whimper, not a bang” scenario. However, it seems that dinosaurs did go out with a bang. A big one. Ammonoids seem to have been brought to the brink with nearly marine mass extinctions during their tenure on Earth, and it was no different with that late-Cretaceous extinction. Ammonoids recovered once again, and their lived in the late Cretaceous, but the end-Cretaceous extinction marked their final appearance as they went the way of and other iconic animals.

The dates are controversial, but it appears that after hundreds of millions of years of using various molecules as electron donors for photosynthesis, began to split water to get the donor electron, and oxygen was the waste byproduct. Cyanobacterial colonies are dated to as early as 2.8 bya, and it is speculated that may have appeared as early as 3.5 bya and then spread throughout the oceans. Those cyanobacterial colonies formed the first fossils in the geologic record, called . At Shark Bay in Australia and some other places the water is too saline to support animals that can eat cyanobacteria, and give us a glimpse into early life on Earth.

Then why do the plants get rid of all the oxygen they produce during photosynthesis

Photosynthesis describes the process that plants use to convert light energy, water, and carbon dioxide into sugar and oxygen. Photosynthesis is used by plants, some bacteria such as algae, and some animals such as mollusks. Scientists currently believe that our modern atmosphere could not exist the way it does without the photosynthesis process and the surrounding carbon cycle that it plays a part in. Not only does photosynthesis affect the atmosphere, but it also affects the food cycle here on Earth. Plants use photosynthesis to create their own food. Small creatures eat these plants and absorb their energy. Larger animals eat the smaller ones and also absorb their energy. Eventually, the largest animals die and their energy is returned to the soil where it is absorbed by plants. All living organisms either benefit from photosynthesis directly or indirectly, including humans.

The plants and cyanobacteria (which use water as a hydrogendonor and produce oxygen) have Photosystems I and II, whereas theless highly evolved other photosynthetic bacteria(which do notuse water as their hydgrogen donor and do not produce oxygen)have only Photosystem I.

During the night, plants breathe in oxygen

At night, plants resort to respiration, wherein they use oxygen to convert sugar into energy.


In case of photosynthesis, carbon dioxide and water react in the presence of light energy derived from sunlight to produce sugar and oxygen.

BBC - GCSE Bitesize: Photosynthesis summary

Plants produce oxygen as a waste product ofmaking sugar using sunlight, carbon dioxide, andwater. If a plant needs energy, but doesn't havesunlight, then it can burn the sugar that it madeback when it had sunlight, and doing so requiresoxygen.

Respiration - humans, body, used, water, process, …

Photosynthetic organisms can be divided into two classes:those which produce oxygen and those which do not. Photosyntheticbacteria do not produce oxygen (in fact some of them calledanaerobes cannot tolerate oxygen) and this is considered a moreprimitive type of photosynthesis (in which the hydrogen donor ishydrogen sulfide, lactate or other compounds, but not water).Plants and one type of bacteria (cyanobacteria) do produceoxygen, an evolutionarily more advanced type of photosynthesis(in which the hydrogen donor is water).

The term respiration has two relatively distinct meanings in biology

Plants can do two importantthings:
Use energy from the sun to turnCO2 (carbon dioxide) and H2O(water) into sugar(C6H12O6) withoxygen (O2) left over. This isphotosynthesis.

Butwhat happens at night when there is no sunlightwhich is needed in photosynthesis? Interestingly,in order to maintain their metabolism and continuerespiration at night, plants must absorb oxygenfrom the air and give off carbon dioxide (which isexactly what animals do). Fortunately for all ofus oxygen breathers, plants produce approximatelyten times more oxygen during the day that whatthey consume at night.
