In phloem movement, ____ cannot serve as a sink.

Question

Quizplus · Accepted Answer

Sinks in the context of phloem movement refer to parts of the plant where sugars and nutrients are being delivered for use or storage. Young leaves, young roots, developing fruits, and tulip bulbs after blooming can all serve as sinks because they require nutrients for growth, development, or storage. Soil, however, cannot serve as a sink because it is not a part of the plant and does not directly utilize the sugars transported by the phloem.
