Concept:Photosynthesis is the process by which green plants make food using sunlight, carbon dioxide, and water.
In this process, carbon dioxide is absorbed, not released.
Explanation:Sunlight energy is absorbed by chlorophyll during photosynthesis.
Water is split into hydrogen and oxygen through photolysis.
Oxygen is evolved as a by-product into the atmosphere.
Carbon dioxide is taken in from the air to produce glucose.
Evolving carbon dioxide would be respiration, not photosynthesis.
Thus, the process that does not occur in photosynthesis is the evolution of carbon (IV) oxide.
Answer:B. Carbon (IV) oxide is evolved.
