What was neil contribution to photosynthesis
  • 1 answers

Meghna Thapar 4 years, 4 months ago

van Niel, C. B. Cornelis Bernardus van Niel was a Dutch microbiologist whose experiments with bacteria helped explain how photosynthesis occurs in plants. Sulfur bacteria particularly interested van Niel, because there was a controversy in the early 1900s concerning the bacteria. 

Jan Baptista van Helmont (1580-1644) partially discovered the process of photosynthesis. He grew a willow tree in a weighed amount of soil. ... As the weight of the soil had hardly changed, van Helmont concluded that plant growth cannot only be due to minerals from the soil. Photosynthesis was partially discovered in the 1600's by Jan Baptista van Helmont, a Belgian chemist, physiologist and physician.
