Which gas is a byproduct of photosynthesis? (2023)

Step 1: Understand what photosynthesis is. It is the process by which plants make their own food using sunlight.
Step 2: Know that photosynthesis occurs in two main stages: light-dependent reactions and light-independent reactions.
Step 3: Focus on the light-dependent reactions, which happen when sunlight is available.
Step 4: During these reactions, plants take in carbon dioxide and water.
Step 5: The energy from sunlight helps convert these into glucose (food) and oxygen.
Step 6: Recognize that the oxygen produced is not needed by the plant and is released into the air.
Step 7: Conclude that the gas released as a byproduct of photosynthesis is oxygen.
