If the rate of translocation of food is slow,what will be the effect on photosynthesis?

$A$: Dark reactions of photosynthesis are temperature-controlled processes.
$R$: Most of the reactions are enzymatic in nature.

The law of limiting factors was proposed with particular reference to photosynthesis. Identify the scientist who proposed this law.

What is the common value of $PQ$ (photosynthetic quotient) of a leaf?

Transpiration ratio is the ratio of moles of ${H_2}O$ transpired to moles of $CO_2$ fixed. This ratio is a measure of:
