Question

Quizplus · Accepted Answer

In late spring, most plants have active leaves that are photosynthesizing and producing sugars, which are the main nutrients transported through the phloem. The leaves are the source of these sugars, and the sink is often the growing apical meristem or developing fruits. Therefore, phloem transports sugars from the leaf source to the apical meristem or fruit sink. None of the other options are consistent with typical phloem transport in plants.
