Vedclass · Answer

(A) The translocation of food (sucrose) in phloem is bidirectional because it can move from source to sink in different directions depending on the plant's needs.$A$ is correct because phloem transport can occur upwards or downwards.$R$ is correct because the source (where sugar is produced,e.g.,mature leaves) and the sink (where sugar is consumed or stored,e.g.,roots,fruits,or young leaves) relationship is variable; a sink can become a source and vice versa depending on the season or developmental stage of the plant.Since the direction of translocation depends on the variable source-sink relationship,$R$ is the correct explanation for $A$.

$A$ : The translocation in phloem is bidirectional.
$R$ : The source and sink relationship is variable.
