Vedclass · Answer

(B) The movement of phloem sap is primarily from source to sink. However,this direction can be bidirectional depending on the seasonal needs of the plant. Specifically,during the early spring,the sugar stored in roots or stem organs (acting as sources) is moved to the developing buds (acting as sinks) to support new growth. Therefore,when the buds are about to develop or sprout,the direction of transport reverses or becomes bidirectional to supply nutrients from storage organs to the growing regions.
