Question

Quizplus · Accepted Answer

Sugars are initially synthesized in the mesophyll cells of leaves and then move through the symplast, which is the interconnected cytoplasm of cells via plasmodesmata. They can move through either the symplast or apoplast (the latter being the network of cell walls and intercellular spaces) of other cells as they travel towards the sieve tube elements. Finally, they enter the symplast of the sieve tube elements for transport throughout the plant.
