EVERYDAY SCIENCE

Detailed explanation-1: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Detailed explanation-2: -Plants “eat” sunlight and carbon dioxide to produce their own food and food for the millions of other organisms dependent on them. A molecule, chlorophyll (Chl), is crucial for this process, since it absorbs sunlight.

Detailed explanation-3: -Plants need both carbon dioxide and oxygen for survival.

Detailed explanation-4: -Plants use sunlight, carbon dioxide and water to make their food and this process is called photosynthesis. During this process oxygen is released into our atmosphere.

Detailed explanation-5: -Plants, like animals, take in oxygen and give out carbon dioxide during respiration. Only during photosynthesis, plants take in carbon dioxide and release oxygen as a byproduct.
