If phloem is damaged in a plant, what effect may occur on roots?
Answer and explanation
Correct answer: Less food made in leaves will reach the roots
The governing concept is translocation through phloem. Leaves produce sugars, mainly sucrose, by photosynthesis, and the phloem transports these organic nutrients from source tissues to sinks such as roots, fruits and growing regions. If phloem is damaged, the movement of food to roots may be reduced or interrupted, limiting their growth and respiration. Therefore option A is correct. Xylem, not phloem, carries water, and roots neither pump blood nor form alveoli.
