Answer:
Photosynthesis is when a plant makes food for itself and releases oxygen.
Step-by-step explanation:
Photosynthesis takes place in the chloroplast of a plant cell, the plant absorbs the light from the sun, takes in carbon dioxide (CO2), and absorbs water from either water on the leaves, or ground water soaked up by plant roots. The light, water, and carbon dioxide get turned into glucose (plant sugar) and oxygen. For humans, they take in sugar and oxygen, and using cellular respiration, they turn the oxygen and sugar into carbon dioxide.
