i-r, ii-s, iii-p, iv-q
T.W. Engelmann plotted the first Action Spectrum, a curve depicting the relative rates of photosynthesis at different wavelengths of light.
Fredrick Blackman proposed the Law of Limiting Factor. According to this law, If a chemical process is affected by more than one factor, then its rate will be determined by the factor which is nearest to its minimal value.
Melvin Calvin gave the concept of Dark reaction, the chemical processes of photosynthesis occurring independent of light.
Robin Hill gave the concept of Light reaction which implies that the light-dependent reaction of photosynthesis is a result of a series of redox reactions and a suitable terminal electron acceptor is required for that reaction to occur.
