Vedclass · Accepted Answer

Xylem is responsible for the upward movement of water.

Vedclass · Answer

(C) $\Rightarrow$ In a girdling (ring) experiment,the phloem is removed,which stops the downward translocation of food (sucrose) to the roots. $\Rightarrow$ However,the xylem remains intact initially,allowing water to move upward to the leaves. $\Rightarrow$ The leaves remain green for some time because they continue to perform photosynthesis using the supplied water. $\Rightarrow$ Eventually,the roots die due to a lack of food supply (as phloem is blocked),which in turn stops the absorption of water and minerals. $\Rightarrow$ Consequently,the entire plant,including the leaves above the girdle,eventually wilts and dies because the root system is no longer functional.
