Direction of movement of sugar in phloem

WebThe movement in phloem is bidirectional, whereas, in xylem cells, it is unidirectional (upward). Because of this multi-directional flow, coupled with the fact that sap cannot move with ease between adjacent sieve-tubes, it is not unusual for sap in adjacent sieve-tubes to be flowing in opposite directions. Sources and sinks [ edit] WebOct 26, 2024 · The mechanism of phloem loading has been the " sucrose−H+ s u c r o s e − H + symport." In this process, the plant takes positively charged protons (i.e., hydrogen cations) and pumps them through...
