Priestley, England, discovers that plants can
"purify" air that has been "burned out" by a
Ingenhousz, The Netherlands, demonstrates that
the plant in Priestley's experiment is dependent
on light and its green parts.
||Several researchers show that carbon
dioxide and water are stored as organic matter by
Germany, points out that plants store solar
energy in organic matter.
Willstätter, Germany, (Nobel Prize 1915)
suggests that chlorophyll plays an active role in
Niel, USA, proposes that photosynthesis is based
on oxidation-reduction reactions and that the
primary reaction is a photolysis of water
followed by oxygen evolution.

hundred chlorophyll molecules cooperate in

and carbon dioxide fixation are separate
Fischer, Germany, solves the chemical
structure of chlorophyll. (Nobel Prize 1930 for

unravel the reactions of carbon dioxide
USA, discovers light-dependent synthesis of ATP
and Fay Bendall, England, and independently Louis
Duysens, The Netherlands, show how two separate
photosystems cooperate in plants.
Parson, USA, confirms Duysens' hypothesis (1956)
that chlorophyll is oxidized in the primary
reaction of photosynthesis.
