Blackman demonstrated that increasing illumination increased the photosynthetic rate upto a point when CO2 becomes limiting. If light was not limiting, temperature becomes limiting. Emerson found that maximum CO2 fixation could be achieved with brief flashes of light. Mark the correct statement in the following
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 if CO2 is present
Answer
Photosynthesis consists of a light and dark reaction
