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: -Carbon dioxide is essential for the plants to sustain, as it is the carbon fixed from the carbon dioxide during photosynthesis is used for synthesizing glucose. This glucose is then later used during cellular respiration to make ATP, the energy molecule.
Detailed explanation-3: -Carbon dioxide plays an important part in vital plant and animal process, such as photosynthesis and respiration. These processes will be briefly explained here. Green plants convert carbon dioxide and water into food compounds, such as glucose, and oxygen. This process is called photosynthesis.
Detailed explanation-4: -Plants take in – or ‘fix’ – carbon dioxide from the atmosphere during photosynthesis. Some of the carbon is used for plant growth, and some of it is used in respiration, where the plant breaks down sugars to get energy.
Detailed explanation-5: -It is used by plants in the process of photosynthesis for preparation of their own food in presence of the sunlight. It is also used in fire extinguishers as the gas is noncombustible. Carbon dioxide is used in the preparation of dry ice which is used as a refrigerant.
