Vedclass · Answer

(D) $(1)$ Julius von Sachs provided evidence for the production of glucose when plants grow. He demonstrated that glucose is usually stored as starch.$(2)$ In $PS-II$ (Photosystem-$II$),the reaction center chlorophyll-$a$ has an absorption peak at $680 \, nm$. Therefore,it is also called $P680$.$(3)$ Since both statements contain incorrect pairings or values in the original prompt,we identify the correct scientific facts: Julius von Sachs is the correct scientist for the glucose/starch experiment,and $680 \, nm$ is the correct wavelength for $PS-II$.

Select the correct option:
$(1)$ Julius von Sachs / $T$. $W$. Engelmann proved with evidence that glucose is produced when plants grow.
$(2)$ In $PS-II$,maximum light absorption occurs at a wavelength of $680 \, nm / 800 \, nm$.
