What is carbon dioxide for Class 6?
Carbon Dioxide: Carbon dioxide is a gas produced during respiration. It is also produced on burning of organic substances. It is used by plants for photosynthesis. Composition of Air: Air is a mixture of nitrogen, oxygen, carbon dioxide, water vapour and a few other gases.Jun 15, 2022
What is the importance of carbon dioxide Class 6?
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.
Why is carbon dioxide important for plants Class 6?
Plants need CO2 to prepare its food by the process of photosynthesis.
Why do plants need carbon dioxide Class 6?
Plants need CO2 to prepare its food by the process of photosynthesis.
What is the function of carbon dioxide Class 6?
CO2 absorbs the heat radiated by the earth and keep the planet warm. It is essential for plant life but excess of CO2 leads to global warming.
Why do plants need carbon dioxide Class 4?
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.Jul 15, 2022
How is carbon dioxide important to plants Class 5?
Carbon dioxide is a necessary element of photosynthesis in plants. It is used in optimum amount by plants to make their food. But a high concentration of carbon dioxide can damage the plant. High concentration of carbon dioxide is not only harmful to plants but also to environment.
What is the importance of oxygen and carbon dioxide Class 6?
Oxygen is important for life. It is important for respiration in all living oragnisms. Carbon dioxide is a greenhouse gas and helps to maintain the temperature on earth.
What is the importance of oxygen Class 6?
Oxygen helps to burn food and release energy. Oxygen helps in burning or combustion. Oxygen helps in breathing or respiration.
How is oxygen and carbon dioxide balanced in the atmosphere Class 6?
Plants take up carbon dioxide from air and give out oxygen during photosynthesis. Animals take up oxygen and release carbon dioxide during respiration. This maintains a balance between oxygen and carbon dioxide in the atmosphere.
What is the importance of oxygen answer?
Oxygen helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.
