What is photosynthesis very short answer?
Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
What is photosynthesis and explain?
Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the “fuel” used by all living things.
What is photosynthesis kid definition?
Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas. Chlorophyll is a substance in all green plants, especially in the leaves. Plants take in water from the soil and carbon dioxide from the air.
What is photosynthesis for 5th graders?
Photosynthesis is the big name for the process by which plants convert energy from sunlight into energy for food. This process also requires water and carbon dioxide. When this happens the water, carbon dioxide and sunlight join together to form a sugar called glucose, plus water, and oxygen.
What is photosynthesis equation for kids?
Photosynthesis also has an equation. Sun, water, and carbon dioxide are the ingredients used in the equation. Oxygen and glucose are made in the process, which means that they are the products. Thus we can say that, in the photosynthesis equation, sun, water, and carbon dioxide change into oxygen and glucose.
What is carbon dioxide for kids?
Carbon dioxide (CO2) is a chemical compound. It is a gas at room temperature. It is made of one carbon and two oxygen atoms. People and animals release carbon dioxide when they breathe out. Also, every time something organic is burnt (or a fire is made), it makes carbon dioxide.
Is carbon dioxide bad for kids?
Climate change is not the only way carbon dioxide can harm you and your family. It can also directly cause cognitive problems when exposed to moderate to high levels indoors. At levels commonly found in schools and meeting rooms, kids can experiences issues with focus related to the CO2 in the room.
How is carbon dioxide made for kids?
Carbon dioxide is a molecule that contains two oxygen atoms and one carbon atom. It can be found as a gas in the air, or as a solid in the form of dry ice, which is very cold. Carbon dioxide is produced from breathing and from burning certain substances called fossil fuels.
How do you teach carbon dioxide?
Distribute candles and cups to each group. Ask groups to put about 2 tablespoons of baking soda in their cup. Next, groups will add about 2 tablespoons of vinegar to their cup and allow it to fizz. This will create carbon dioxide.
How is the balance of carbon dioxide and oxygen maintained in nature?
The balance of oxygen and carbondioxide is maintained in the atmosphere by the oxygen released by plants during photosynthesis and carbondioxide released by human,animals etc. in the atmosphere. The balance of oxygen and carbondioxide is made due to respreration and photosinthesis.
What is the importance of maintaining the balance of oxygen and carbon dioxide in the atmosphere?
Animals release carbon-dioxide during respiration which is absorbed by plants. In this way the oxygen and carbon dioxide cycle goes on. Since forests contain a large number of plants and trees, they help in maintaining the balance between oxygen and carbon dioxide in the atmosphere.
How do the carbon dioxide oxygen level maintained explain?
Photosynthesis – plants produce their own food in the form of glucose using the process of photosynthesis. This process uses sunlight (and so only occurs during the day) to remove carbon dioxide from the atmosphere and release oxygen.
How will you describe in your own words the sequence of oxygen carbon dioxide and blood flow?
Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled. Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide.
Where does the exchange of oxygen and carbon dioxide occur?
During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
What is responsible for exchange of oxygen and carbon dioxide?
Bronchioles end in tiny air sacs called alveoli, where the exchange of oxygen and carbon dioxide actually takes place. Each person has hundreds of millions of alveoli in their lungs. This network of alveoli, bronchioles, and bronchi is known as the bronchial tree.
Where is the site of oxygen and carbon dioxide exchange in the lungs quizlet?
alveoli
How do the lungs remove carbon dioxide?
CAPILLARIES are blood vessels in the walls of the alveoli. Blood passes through the capillaries, entering through your PULMONARY ARTERY and leaving via your PULMONARY VEIN. While in the capillaries, blood gives off carbon dioxide through the capillary wall into the alveoli and takes up oxygen from air in the alveoli.
