C) Hatch and Slack
D) Emerson and Arnold
Correct Answer: D
Solution :
Emerson and Arnold (1932) established lighi and dark phases in photosynthesis with the help of flashing light and Ermersonconcludec two distinct photochemical process in light reaction of photosyntehsis. Calvin traced the path of carbon fixation by using \[\left( 14C{{O}_{2}} \right)\] and gave \[{{C}_{3}}\]cycle also known as Calvin cycle. Hill (1937) performed that \[{{O}_{2}}\]evolved in light reaction of photosynthesis in absence of \[C{{O}_{2}}.\]Hatch and Slack (1965) discovered supplementory mechanism of \[C{{O}_{2}}\]fixation called C4 pathway in certain tropical plants.
