≡Photosynthesis, a term that means “synthesis using light
Photosynthesis, a term that means “synthesis using light,” is generally defined as the process by which an organism obtains its food. Process of photosynthesis: For the production of organic matter, plants need and carbon dioxide, solar energy, water and mineral salts, and as a result, there is release of oxygen and water vapor to the environment. Sunlight is absorbed by chlorophyll, present in the leaves, and provides the energy the plant needs to produce food; The leaves receive carbon dioxide from the air and release oxygen and water vapour, and the roots absorb water with dissolved mineral salts from the soil. It is estimated that 40% to 50% of the oxygen present in the atmosphere comes from the algae that live in the oceans and lakes.
