Some unknown facts about Photosynthesis
Green plants bind solar energy as a chemical energy through photosynthesis, first to glucose and then to other organic compounds such as carbohydrates, proteins, fats, vitamins, etc. So solar energy is the main source of all energy.
In 1896, the scientist Bernes coined the term photosynthesis, which is a combination of the Greek word photos, meaning light, and synthesis. The synthesis of something in the presence of light is called photosynthesis.
Melvin Kelvin, the son of non-resident Russian parents, was born in 1911 in Minnesota, USA. In 1956, he observed the 'Kelvin cycle' in the chlorella plant. He proved that the first organic compound produced in photosynthesis was phosphoglyceric acid (PGA). In 1961, scientist Kelvin won the Nobel Prize in Biology. This great scientist died in 1998.
Contribution of Scientists in Photosynthesis: -
1) J. B. Van Helmont (J. B. Van Helmont-1648): Proves that plants prepare food by absorbing fertilizer and water from the soil.
2) Stephen Hales (1727): Leaves play an important role in the nutrition of plants.
3) Joseph Priestly (1772): During photosynthesis, the plant releases oxygen gas.
4) Jean Senebier (1796): Plants absorb carbon dioxide gas during photosynthesis.
5) Pelletier (1818): The first green pigment in the plant is called chlorophyll.
6) Robert Von Mayer (1844): During photosynthesis, solar energy is converted into chemical energy.
6) Blackmann (1905): The process of photosynthesis is done in two stages - light reaction and dark reaction.
6) Samuel Ruben (1941): Using oxygen isotope (O18) proved that the oxygen produced in the process of photosynthesis is produced from water.
9) Benson & Calvin (1956): Observed the 'Kelvin cycle' in a plant called Chlorella.
