State the direction of movement of food in the phloem.
GeneralClass 12AllAnswered 27 Mar 2026
Answer
The direction of food movement in phloem is bidirectional, meaning it can move:
- Upwards (from roots to shoots during early spring when stored food is mobilized)
- Downwards (from leaves to roots, stems, fruits during active photosynthesis)
Key Concept: Movement is from source (site of synthesis or storage) to sink (site of utilization or storage), irrespective of gravitational direction.
