Why is food transport in phloem considered energy dependent?

Answer and explanation

Correct answer: Because food must be actively moved from the source to parts that need it

Phloem translocation distributes sugars such as sucrose from a source, usually a photosynthesising leaf, to sinks such as roots, fruits, seeds, or growing tissues. Loading sugars into sieve tubes and maintaining the pressure gradient require metabolic energy, especially from companion cells. Transport can occur in different directions according to demand. Therefore A is correct; the other choices wrongly describe phloem as dead tissue or a water-only pathway.
