If phloem is damaged at one point in the stem, what long-term effect may occur on roots?
Answer and explanation
Correct answer: Roots will receive less food
The governing concept is translocation through phloem. Leaves prepare sugars by photosynthesis, and phloem distributes these food substances to growing and storage organs, including roots. A damaged region can interrupt or reduce movement of sugars beyond that point, so roots may receive less food for respiration, growth and storage over time. Therefore option A is correct. Xylem carries water, and the other options incorrectly apply animal functions to roots.
