How Do Plants Produce Oxygen?

KOMPAS.com Oxygen is one of the gases that are essential for humans. One of the biggest oxygen producers are plants. How plants produce oxygen? Here is the explanation!

Plants can produce oxygen through the process of photosynthesis. As we know, photosynthesis uses sunlight, water (H2O), and carbon dioxide (CO2) to form sugar and oxygen.

Plants depend on water and sunlight to produce oxygen. The process of photosynthesis that produces oxygen is carried out in the thylakoid membrane.

Reported from Sciencing, thylakoid membrane is the inner membrane of the chloroplast where light reactions of photosynthesis.

Oxidation of water (H2O)

Reported from Encyclopedia BritannicaThe oxygen (O2) produced by plants comes from water (H2O) which is absorbed by plants from their environment.

This was first proposed by a biologist from the Netherlands named Cornelis van Niels and supported by other scientists.

To prove it, scientists used the oxygen isotope into the water and observe the results of photosynthesis.

They later discovered that water containing the oxygen isotope () will produce the oxygen isotope () through photosynthesis.

The results of this experiment are proof that oxygen is produced from water through the process of photosynthesis.

Reported from National Geographicin the thylakoid membrane water (H2O) is oxidized to lose electrons.

This causes water (H2O) to release its hydrogen ions and form oxygen (O2).

The resulting oxygen is then released into the air through the leaf stomata.

Scientists estimate that one leaf of a plant can produce about five milliliters of oxygen per hour through the process of photosynthesis.
