Consider the following statements:
(A) The portion of the spectrum between 500 nm and 800 nm is also referred to as photosynthetically active radiation (PAR).
(B) Magnesium, calcium, and chloride ions play prominent roles in the photolysis of water

- a)A is true but B and C are false
- b)A and B are false but C is true
- c)B is true but A and C are false

The portion of the light spectrum utilised by plants for photosynthesis is better known as photosynthetically active radiation (PAR). Plants utilise 400-700 nm wavelength of light in photosynthesis; hence, it constitutes PAR. The green plants have photosynthetic pigments chlorophyll a and b which show maximum absorption of light in red (620nm — 750nm) and blue (450nm) regions of the absorption spectrum. Hence, the maximum absorption of light by green plants occurs in 400nm — 700nm wavelength of light.
The most optimum region for photosynthesis is 600-680 nm.
In the light reaction, the two photosystems, viz. PS I and PS II participate in two schemes- cyclic and non-cyclic photophosphorylation.
In the primitive environment, free oxygen was not available, and when the photosynthetic forms began to get evolve, the primitive bacteria (Eubacteria) derived their ATP through cyclic photophosphorylation. This is an anoxygenic photosynthetic process with common features like:
- There is only one reaction centre (P700) of only one photosystem (PS-I).
- There is no splitting of the water molecules and hence, no evolution of oxygen.
- The electron comes back, after getting de-energized completely, to the same reaction centre.
- This cyclic event occurs when there is a low intensity of light (of wavelength more than 680 nm) is available or there is an improper CO2 fixation rate.
Thus, In cyclic photophosphorylation, oxygen is not released (as there is no photolysis of water) and NADPH is also not produced.
Magnesium and calcium do not play any role during photosynthesis. A major role is played by manganese and chloride ions.
