The first step in photosynthesis is
Ionisation of water
Fixation of co2
Excitation of chlorophyll-a due to light
Formation of ATP
The light depended splitting of water molecules is called
Oxidation
Hydrolysis
Photolysis
Reduction
The CO2 concentration at which the rate of photosynthesis and rate of respiration are equal.
Carbondioxide compensation point
The threshold value
Both(a)and (b)
None of these
