In photolysis of water(a stage in light reactions),light activated chlorophyll splits the water molecule into protons,electrons and oxygen. Since the concentration of oxygen inside the plant is more than the atmosphere, oxygen diffuses out.
Oxygen is the gas given out by green plants during photosynthesis.
Plants obtain oxygen during photosynthesis from water molecules.
Why is it important that plants give off oxygen during photosynthesis
the manufactured by plants during photosynthesis is glucose.
During photosynthesis, plants release oxygen and not carbon dioxide.
Most of autotrophic plants get major amount of oxygen from photosynthesis. During night, when there is no photosynthesis, oxygen by plants is obtained from air However, the amount of oxygen released during photosynthesis by plants is manifold of their requirement for respiration.
During the process of photosynthesis, plants release oxygen into the air. This process is sometimes called the oxygen cycle when it refers to the role of plants in the production of oxygen for the planet.
Plants release oxygen during photosynthesis.
Oxygen is one of the by-products of photosynthesis. It comes from the breakdown of water molecules in plants during photosynthesis.
The waste product for plants in photosynthesis is oxygen. During photosynthesis, plants use carbon dioxide and water to produce glucose and oxygen. The oxygen is released into the atmosphere as a byproduct of the process.
Oxygen
During photosynthesis, plants release oxygen gas as a byproduct. This occurs when plants take in carbon dioxide from the environment and, through the process of photosynthesis, convert it into glucose and oxygen.
