$I$ and $II$

Vedclass · Answer

(A) $DCMU$ ($3$-($3$,$4$-dichlorophenyl)$-1,1-$dimethylurea) is a herbicide that acts as an inhibitor of non-cyclic electron transport in photosynthesis.$PMA$ (Phenylmercuric acetate) is a fungicide that also acts as an anti-transpirant by reducing transpiration.Colchicine is an alkaloid that inhibits mitosis by preventing the formation of spindle fibers; it does not cause male sterility.Soilrite is a commercial medium used for the encapsulation of somatic embryos,but it is not composed of sodium alginate (sodium alginate is used for the encapsulation process itself).Therefore,the correct pairs are $I$ and $II$.

Column-$I$	Column-$II$
$a.$ $OEC$	$(i)$ Primary e-acceptor
$b.$ $NADP$ reductase	$(ii)$ Photolysis of $H_2O$
$c.$ Succinyl $CoA$	$(iii)$ Outer surface of thylakoid membrane
$d.$ Phaeophytin	$(iv)$ Chlorophyll synthesis

Read the following and choose the option containing the correct pair:
$I.$ $DCMU$: Herbicide,Inhibitor of non-cyclic electron transport
$II.$ $PMA$: Fungicide,Reduces transpiration
$III.$ Colchicine: Alkaloid,Causes male sterility
$IV.$ Soilrite: Sodium alginate,Encapsulation of somatic embryos
