Which statement correctly describes the movement of solutes in the symplast pathway?
ACell surface membranes regulate the selective absorption of solutes into the symplast pathway.
BPlasmodesmata control the movement of solutes from the symplast pathway to the apoplast pathway.

DThe movement of solutes through plasmodesmata in the symplast pathway is prevented in the endodermis by suberin.
