They use most of the oxygen to make more glucose.

|
They release most of the oxygen into the atmosphere.

|
They release most of the oxygen into the soil.
|
|
|
They use most of the oxygen to produce carbon dioxide.

Detailed explanation-1: -The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
Detailed explanation-2: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.
Detailed explanation-3: -Scientists estimate that roughly half of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic plankton-drifting plants, algae, and some bacteria that can photosynthesize. One particular species, Prochlorococcus, is the smallest photosynthetic organism on Earth.
Detailed explanation-4: -Plants are active photosynthesisers i.e., they take up carbon dioxide from the atmosphere and using the energy from sunlight and water they convert it into carbohydrate molecules. During this process, plants produce oxygen. They utilise the oxygen produced for respiration.
Detailed explanation-5: -Energy consumption by cellular respiration Interestingly, this process also uses oxygen in the same way as humans use oxygen for breathing. Fortunately, photosynthesis also uses CO2 and produces 10 times more oxygen, so plants create much more oxygen than they use. And that’s a good thing.
