What is photosynthesis and how does it work?
What is photosynthesis and how does it work?
Green plants carry out ‘photosynthesis’, a physico-chemical process by which they use light energy to drive the synthesis of organic compounds. Ultimately, all living forms on earth depend on sunlight for energy. The use of energy from sunlight by plants doing photosynthesis is the basis of life on earth.
What is the oxidation product of H2O in photosynthesis?
In green plants H2O is the hydrogen donor and is oxidised to O2. Someorganisms do not release Oduring photosynthesis. When H 2 2S, insteadis the hydrogen donor for purple and green sulphur bacteria, the‘oxidation’ product is sulphur or sulphate depending on the organismand not O2. Hence, he inferred that the O
What is the overall equation for photosynthesis?
Photosynthesis provides the energy to reduce carbon required for the survival of virtually all living systems on our planet. It creates molecular oxygen necessary for the survival of oxygen consuming organisms. The overall equation for photosynthesis is deceptively simple (eq 5.1). 6 CO26 H2O hν
What happens to the glucose produced during photosynthesis?
The glucose produced during photosynthesis is then used to fuel various cellular activities. The by-product of this physio-chemical process is oxygen. A visual representation of the photosynthesis reaction Photosynthesis is also used by algae to convert solar energy into chemical energy.
Photosynthesis is the process through which plants convert light energy from the sun to chemical energy. The chemical energy is then stored as sugar.
What is the end product of photosynthesis?
The photosynthesis process occurs in all plants and algae, as well as in some bacteria species. In addition to light energy, the process also requires water and carbon dioxide. And the end product is sugar. Photosynthesis takes place inside plant cells in small things called as chloroplasts using chlorophyll – the green pigment in plants.
How is oxygen liberated as a by-product of photosynthesis?
Oxygen is liberated as a by-product and light is considered as a major factor to complete the process of photosynthesis. Photosynthesis occurs when plants use light energy to convert carbon dioxide and water into glucose and oxygen.
What happens to carbon dioxide and water during photosynthesis?
This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
