Vedclass · Answer

(B) In plants,the transport of substances occurs through two main vascular tissues: $Xylem$ and $Phloem$.$Xylem$ is responsible for the unidirectional transport of water and minerals from the roots to the aerial parts of the plant.$Phloem$ is responsible for the transport of food (sucrose) from the source (leaves) to the sink (roots,fruits,or storage organs).Since the source and sink can change depending on the plant's needs (e.g.,during spring,stored food moves from roots to developing buds),the transport in $Phloem$ is bidirectional. Therefore,the correct answer is $Phloem$.
