Bidirectional from leaves to stem and roots for consumption and storage.

Vedclass · Answer

(B) In vascular plants,the phloem is responsible for the translocation of food (primarily sucrose) from the source (usually leaves) to the sink (roots,fruits,seeds,or growing regions). Unlike xylem,which transports water and minerals unidirectionally (upwards),phloem transport is bidirectional. This is because the source and sink relationship can be variable; for example,in early spring,the roots act as a source of stored sugars,which are transported upwards to the developing buds. Therefore,the transport of organic and mineral nutrients in the phloem is bidirectional.
