• A. R. Mayer
• B. Willstatter and Stoll
• C. Arnon
• D. Calvin.

Answer 1

The correct option is A R. Mayer

Photosynthesis is a process by which green plants manufacture their food with the help of carbon dioxide and water in the presence of sunlight. When light energy is absorbed by photosynthetic pigment chlorophyll, then it gets exited and photosynthetic reaction center loses an electron. In this way, light energy is converted to chemical energy. Conversion of light energy into chemical energy is the primary event in photosynthesis. R. Mayer stated that in photosynthesis light energy is converted into chemical energy. He also proposed that the sun is the ultimate source of energy utilized by living organisms.
