Because of photolysis. An enzyme splits water and electrons for photosystem II, hydrogen ions and oxygen that diffuses out of the leaves is the result here.
In general outline, photosynthesis is the opposite of cellular respiration. CO2+ H2O+sunlight ----> O2 + H2O +carbohydrates.It uses carbon dioxide and the energy from sunlight to make carbohydrates and oxygen (a waste product from plants).
They give of Oxygen. Glucose is produced as main product
Why is it important that plants give off oxygen during photosynthesis
Plants produce oxygen when exposed to light. They do this by the process of photosynthesis. The oxygen comes from the splitting of water molecules to produce hydrogen ions and the oxygen is expelled as a waste product.
Oxygen is given off as a by-product os photosynthesis
sugar and oxygen
They produce glucose and oxygen. Oxygen is given off as a gas.
photosynthesis
Oxygen or O2
By using photosynthesis. Photosynthesis releases oxygen as a waste product.
Plants give off oxygen as a waste product through the process of photosynthesis, where they use carbon dioxide to produce energy. This oxygen is released into the atmosphere and is essential for many living organisms, including humans, to breathe and survive.
