FoundationWhat is the stem region between two nodes called?
Need a small nudge?

UnderstandingWhich comparison between xylem and phloem is correct?
Need a small nudge?

Separate the water-conducting pathway from the photosynthate-conducting pathway.

ApplicationA narrow ring of bark containing functional phloem is removed all the way around a young woody stem, but most xylem remains intact. What is the best immediate prediction?
Need a small nudge?

Bark removal can remove outer phloem while leaving inner xylem.

InterpretationA mature leaf exports sucrose to both a developing fruit above it and growing roots below it. Which statement best describes phloem direction?
Need a small nudge?

Direction follows the location of sources and sinks, not a single compass direction.

ConnectionA stem must hold leaves in light, connect roots to leaves, and supply a growing bud with imported sugar. Which feature set best supports all three demands?
Need a small nudge?

Combine mechanical support with both vascular pathways.
