FAQs on Cornelius van Niel’s Experiment Video Lecture - Biology Class 11 - NEET

1. What was the purpose of Cornelius van Niel's experiment?
Ans. The purpose of Cornelius van Niel's experiment was to investigate the process of photosynthesis and understand how certain organisms convert sunlight into energy.
2. How did Cornelius van Niel conduct his experiment?
Ans. Cornelius van Niel conducted his experiment by studying purple sulfur bacteria and green bacteria, which are known to perform photosynthesis using different methods. He carefully observed and analyzed their metabolic pathways to understand the chemical reactions involved in photosynthesis.
3. What were the key findings of Cornelius van Niel's experiment?
Ans. Cornelius van Niel's experiment led to several key findings, including the discovery that different organisms use different electron donors and acceptors during photosynthesis. He also found that the oxygen released during photosynthesis comes from water, rather than carbon dioxide as previously believed.
4. How did Cornelius van Niel's experiment contribute to our understanding of photosynthesis?
Ans. Cornelius van Niel's experiment significantly contributed to our understanding of photosynthesis by providing evidence that photosynthetic organisms use specific electron donors and acceptors. His findings challenged the prevailing belief that all photosynthetic organisms used carbon dioxide as an electron source.
5. What is the significance of Cornelius van Niel's experiment in the field of biology?
Ans. Cornelius van Niel's experiment paved the way for further research in the field of photosynthesis and significantly expanded our knowledge of how organisms convert light energy into chemical energy. His findings revolutionized the understanding of metabolic processes in living organisms and laid the foundation for future studies on energy conversion and biological systems.
