Question

Blackman demonstrated that increasing illumination increased the photosynthetic rate upto a point whenC{{O}_{2}}
becomes limiting. If light was not limiting, temperature becomes limiting. Emerson found that maximumC {{O} _ {2}}
fixation could be achieved with brief flashes of light. Mark the correct statement in the following [CPMT 1988, 89]
A) Only one factor can be limited in photosynthesis
B) Photosynthesis consists of a light and dark reaction
C) The trapping of light by chloroplast is temperature dependent
D) The trapping of light by chloroplast can occur only ifC {{O} _ {2}}
is present
