Oxygen is required for respiration - the process where energy is made available for living. All organisms, including plants and animals, need to respire to have any energy. Energy is required for all life.
The way plants and animals differ is the way they generate the source of the energy. Animals get their energy from food, by eating. Plants get their energy from sunlight, by photosynthesis. In this process, they need carbon dioxide, to fix this energy into a storable form. However, in order to later USE the energy, they need to respire, using oxygen, in the same way that an animal needs to respire with oxygen to use the energy from food.

Plants have mitochondrial cellular respiration that breaks down stored energy and generates ATP. Cellular respiration requires oxygen as a reactant. C6H12O6 + 6O2 => 6CO2 + 6H2O + ENERGY Carbohydrates made during photosynthesis and oxygen are used in this reaction releasing the energy, carbon dioxide, and water.

Plants require oxygen and carbon dioxide for photosynthesis. But oxygen is not taken as a gas for plants. They acquire it as water. Plants synthesize glucose to acquire energy and oxygen gas as a waste product.

Oxygen is required for all materials, in plants it is it's the waste product of photosynthesis. It is needed for all living organisms.

They utilize CO2 and give off O2
