Assertion is correct,but Reason is incorrect.

Vedclass · Answer

(C) The Assertion is correct because chlorophyll $a$ and $b$ absorb light most efficiently in the blue and red regions of the visible spectrum,leading to higher rates of photosynthesis in these regions.The Reason is incorrect because an action spectrum depicts the magnitude of a biological response (such as the rate of photosynthesis) as a function of light wavelength. It does not show the amount of energy absorbed by pigments; that is the definition of an absorption spectrum.

$(2)$ Non-cyclic photophosphorylation	$(b)$ $ATP$ formed
$(3)$ $C_4$ cycle	$(c)$ Meristematic tissue
	$(d)$ High productivity

$A$ : Most of the photosynthesis takes place in the blue and red regions of the spectrum.
$R$ : Action spectrum shows the amount of energy of different wavelengths of light absorbed by pigments.
