Choose the correct pair:

Which of the following is $NOT$ a utility of photosynthesis?

Separate the processes of light reaction and dark reaction from the following:
$I-$ Fixation of $CO_2$
$II-$ Absorption of light
$III-$ Release of $O_2$
$IV-$ Utilization of $ATP$ and $NADPH_2$
$V-$ Synthesis of $ATP$ and $NADPH_2$
$VI-$ Synthesis of glucose
Identify the correct sequence for light reaction and dark reaction respectively.

The statement "We are created by chloroplast" suggests the idea that:

Explain the information about the discovery of $C_3$ and $C_4$ pathways.

Assertion $:-$ There is not a complete one-to-one overlap between the absorption spectrum of chlorophyll $a$ and the action spectrum of photosynthesis.
Reason $:$ Most of the photosynthesis takes place in the blue and red regions of the spectrum,but some photosynthesis does take place at the other wavelengths of the visible spectrum.
