How is food transport in phloem different from water transport in xylem?
Answer and explanation
Correct answer: Food can move both ways in phloem, while water mainly moves upward in xylem
The governing concept is transport in vascular tissues. Xylem carries water and dissolved minerals mainly upward, from roots toward stems and leaves, driven by transpiration and related forces. Phloem translocates food, especially sucrose made in leaves, from a source to sinks such as roots, fruits, or growing tissues. Because sources and sinks can vary, phloem movement may be upward or downward. Therefore, option A is correct; the other choices confuse plant tissues and their functions.
