Final answer:
The formula for photosynthesis is carbon dioxide + water + sunlight → glucose + oxygen. This process transforms these reactants into glucose, a form of sugar, and oxygen gas through sunlight energy.
Step-by-step explanation:
The formula for photosynthesis is a) Carbon dioxide + water + sunlight → glucose + oxygen.
Photosynthesis is a fundamental biological process wherein plants, algae, and certain bacteria convert carbon dioxide (CO₂) and water (H₂O) into glucose (C₆H₁₂O₆) and oxygen (O₂) using the energy from sunlight. This process occurs through a series of complex reactions, involving two main stages known as the light reactions and the Calvin cycle. The overall chemical equation representing photosynthesis is 6CO₂ + 6H₂O + sunlight energy → C₆H₁₂O₆ + 6O₂. Here, six molecules of carbon dioxide and six molecules of water are converted into one molecule of glucose and six molecules of oxygen.
