photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy . During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
What is photosynthesis for kids short answer?
Photosynthesis is the process in which green plants use sunlight to make their own food. ... Green plants use this light energy to change water and carbon dioxide into oxygen and nutrients called sugars. The plants use some of the sugars and store the rest. The oxygen is released into the air.
How does photosynthesis work summary?
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy , which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.
What is the purpose of photosynthesis short answer?
The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use . For the most part, the planet's living systems are powered by this process.
What are the steps of photosynthesis simple?
- Absorption of light. The first step in photosynthesis is the absorption of light by chlorophylls that are attached to the proteins in the thylakoids of chloroplasts. ...
- Electron Transfer. ...
- Generation of ATP. ...
- Carbon Fixation.
How does photosynthesis affect humans?
Through photosynthesis, humans can again breathe in the oxygen that was produced and survive . ... In a way, they are a cycle — plants help humans breathe by providing us with oxygen, and humans help plants “breathe” by providing them with carbon dioxide.
What is photosynthesis in your own words?
The definition of photosynthesis is the process through which plants use water and carbon dioxide to create their food , grow and release excess oxygen into the air. ... An example of photosynthesis is how plants convert sugar and energy from water, air and sunlight into energy to grow.
What occurs in photosynthesis?
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen . ... Then, via respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product.
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. ... In this form the plants can use the glucose ,and water for food and release the oxygen back into the air for consumption by animals, including humans.
Do plants take in oxygen?
Most folks have learned that plants take up carbon dioxide from the air (to be used in photosynthesis) and produce oxygen (as a by-product of that process), but less well known is that plants also need oxygen. Plants, like animals, have active metabolisms, fueling all bodily activities.
What is the important of photosynthesis?
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere . ... Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy.
What is the importance of photosynthesis Class 7?
Photosynthesis helps to maintain a balance between oxygen and carbon dioxide in the atmosphere as it absorbs carbon dioxide and release oxygen. Sunlight is necessary for photosynthesis. Thus sun is the ultimate source of energy for all living organism.
What is photosynthesis explain with diagram?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy . During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
What are the 5 major steps involved in photosynthesis?
- Step 1-Light Dependent. CO2 and H2O enter the leaf.
- Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
- Step 3- Light Dependent. The electrons move down to enzymes.
- Step 4-Light Dependent. ...
- Step 5-Light independent. ...
- Step 6-Light independent. ...
- calvin cycle.
What is the process of photosynthesis Class 7?
The process by which green plants make their own food (like glucose) from carbon dioxide and water by using sunlight energy (in the presence of chlorophyll) is called photosynthesis. ... The leaves of a plant can synthesise food because they contain a green pigment chlorophyll (which is necessary for making food).
How do plants depend on human being?
We all know that plants need carbon dioxide for the preparation of their food . We , humans release carbon dioxide while respiration. So this carbon dioxide is absorbed by the plants. In such way plants are dependent on humans.
