Expert Answer
The phloem is responsible for food transport. This can be explained by a girdling experiment.
On a tree trunk, a ring of bark up to a depth of the phloem layer is removed.
Due to the absence of the phloem layer, the food gets accumulated in the region of the stem just above the ring.
This swollen part of the stem indicates that the food is transported through the phloem.
