Why can transport of food in plants occur in both directions?
Answer and explanation
Correct answer: Food can be sent through phloem wherever it is needed
The governing concept is phloem translocation from a source to a sink. Mature leaves commonly produce sugars, but growing roots, fruits, seeds, stems, and buds may require them at different times. Phloem can therefore move dissolved food from the producing region to the region of use or storage, either upward or downward according to need. Option A is correct; xylem mainly transports water and minerals, not food.
