WebThe fact that oxygen given off by photosynthesis coming from water was proven experimentally by exposing plants first to CO2 and then to H2O that contained an … WebCorrect option is A) Photolysis takes place in the light dependent reaction of the photosynthesis. The reaction can be represented as: H 2O + 2 photons --> 2 e − + 2H + + O. Here, the electrons released are accepted by the photosystem to fulfill the electron gap.

WebPlants produce oxygen, because when they photosynthesize, they take carbon dioxide (CO 2; a gas-form of carbon bonded to two oxygen molecules) and water (H 2 O; an oxygen bonded to two hydrogen atoms) and combine them using light energy to produce sugars and oxygen. This stores the energy in chemical bonds (in the sugars) and releases O 2. WebThe oxygen atoms, however, form oxygen gas, which is a waste product of photosynthesis. The oxygen given off supplies most of the oxygen in our atmosphere. Before photosynthesis evolved, Earth’s atmosphere lacked oxygen altogether, and this highly reactive gas was toxic to the many organisms living at the time.

How much oxygen comes from the ocean? - National Ocean Service
WebOct 14, 2024 · The oxygen comes from the splitting of water. Explanation: During photosynthesis, light will hit pigment cells in photosystem II. The cells absorb this energy which is transferred from cell to cell until the P680 pair of chlorophyll molecules absorb it. WebJul 15, 2024 · The process During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is … WebAnd this is basically the oxygen that is released on this side if the carbons in carbon dioxide are incorporated into the glucose by using the energy from the sun. Okay, so the oxygen given off by photosynthesis comes from water. Okay. Not from carbon dioxide. Glucose is a product, so glucose cannot provide the oxygen. Okay.
