– Photosynthesis is a physiological process that is an ultimate source of oxygen and energy for all living organisms . ... – It fixes and balances the amount of carbon dioxide and oxygen in the atmosphere by plants exhaling oxygen and animals and humans exhaling carbon dioxide.
What is significance of photosynthesis Class 10?
Significance of Photosynthesis:
Photosynthesis is the main way through which the solar energy is made available for different living beings . Green plants are the main producers of food in the ecosystem. All other organisms directly or indirectly depend on green plants for food.
What is the significance of photosynthesis Class 11?
Photosynthesis is a physio-chemical process which uses light energy to produce organic compounds. Photosynthesis is essential as it not only is the primary source of food for living entities but it also releases oxygen into the atmosphere which is required to breathe.
What is photosynthesis explain in short?
Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates . It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. The sugars are used by the cell as energy, and to build other kinds of molecules.
What is the significance 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 the best definition of photosynthesis?
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 the main importance of photosynthesis?
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. The importance of photosynthesis in our life is the oxygen it produces . Without photosynthesis there would be little to no oxygen on the planet.
What are two significance of photosynthesis?
– It fixes and balances the amount of carbon dioxide and oxygen in the atmosphere by plants exhaling oxygen and animals and humans exhaling carbon dioxide. – It helps in the synthesis of organic compounds from inorganic compounds. – It provides nutrition to the plants and thus helps in their growth and development.
What are the two stages of photosynthesis?
Photosynthesis takes place in two sequential stages: The light-dependent reactions; The light-independent reactions, or Calvin Cycle .
What is the definition of photosynthesis ?( 1 point?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar .
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 is photosynthesis explain with diagram?
| Photosynthesis Cellular respiration | The products of photosynthesis are carbon dioxide, water, and energy. The products of cellular respiration are glucose, oxygen, and water molecules. |

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 the significance of photosynthesis in ocean?
Phytoplankton, such as algae, are the plants that make photosynthesis happen in the ocean. These tiny plants live on the surface of the water where they collect their energy from the sun and use it along with nutrients in the water to grow and feed ocean life .
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).
What are the end products of photosynthesis Class 7?
Glucose and oxygen are the final products of photosynthesis.
