Detailed explanation-1: -In the process of photosynthesis, plants create sugars and release oxygen (O2). The oxygen released by the chloroplasts is the same oxygen you breathe every day. Chloroplasts are found in plant cells, but not in animal cells.

Detailed explanation-2: -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-3: -Answer and Explanation: Photosynthesis takes place in the chloroplasts, which are found in the cells in the leaves and stems of plants. The oxygen produced by photosynthesis diffuses into the intercellular space and out of the underside of the leaves through the stomata. This oxygen is then released into the air.
