Which describes the role of oxygen in photosynthesis and cellular respiration?
Oxygen is a reactant in photosynthesis and a product of cellular respiration.

Oxygen is a product of photosynthesis and a reactant in cellular respiration.

Oxygen is produced in both photosynthesis and cellular respiration.

During photosynthesis green plants manufacture their food using carbon dioxide and water in the presence of sunlight. The product of this reaction is formation of food and oxygen gas to the environment. Therefore, oxygen is given off during photosynthesis.

During cellular respiration, organisms use oxggen gas to liberate energy from food. Most times carbon dioxide is the waste product from the reaction.

The statement that describes the role of oxygen in photosynthesis and cellular respiration is oxygen is a product of photosynthesis and a reactant in cellular respiration.

PHOTOSYNTHESIS:

Photosynthesis is the process whereby green plants obtain their food (glucose) using energy from sunlight.

Photosynthesis combines glucose and oxygen molecules to produce carbon dioxide (CO2) and water (H2O).

CELLULAR RESPIRATION:

Cellular respiration is the process whereby living organisms obtain energy by breaking down food molecules in their cells.

Cellular respiration combines carbon dioxide (CO2) and water (H2O) to produce glucose and oxygen as products.

Therefore, the statement that describes the role of oxygen in photosynthesis and cellular respiration is oxygen is a product of photosynthesis and a reactant in cellular respiration.
