During photosynthesis, plants take in ____ and release _______ gas.

During photosynthesis, plants take in carbon dioxide from the air and water from the soil. They use sunlight to turn these into food in the form of carbohydrates. At the same time, they release oxygen into the air. During photosynthesis, plants take in carbon dioxide to make food and give off oxygen, which is important for life on Earth. Hence, the correct answer is carbon dioxide and oxygen. During photosynthesis, plants take in carbon dioxide and give out oxygen, which benefits both plants and animals.
