Detailed explanation-1: -The oxygen released during photosynthesis is from the water. The plants will absorb water as well as carbon dioxide during photosynthesis. Later these water molecules are converted into oxygen and sugar. The oxygen is then released into the atmosphere whereas the sugar molecules are stored for energy.
Detailed explanation-2: -The Two Parts of Photosynthesis In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen from the hydrolysis of water as a byproduct.
Detailed explanation-3: -The splitting of water molecules is called photolysis of water. During the light reaction of photosynthesis, the absorption of light by the chlorophyll results in the loss of the electron from it.
Detailed explanation-4: -Splitting of H2O molecules into hydrogen ions and oxygen in the presence of light and stroma is photolysis.
Detailed explanation-5: -The process This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
