Which substances does phloem mainly transport in a plant?
AWater absorbed by roots upwards only
BFood prepared by leaves downwards
CMinerals from soil into the root cells
DOxygen released during photosynthesis
Answer & Solution
Correct answer: B. Food prepared by leaves downwards
1. The chapter splits transport into water/minerals via xylem and food via phloem.
2. Food is prepared by leaves through photosynthesis.
3. Phloem sieve tubes carry this food to roots, fruits and other parts.
4. So phloem transports food downwards.
