A ring of bark is cut from a tree trunk, destroying the phloem. What stops working?

1. A plant has two transport tissues, and each carries something different. 2. Phloem translocates the food manufactured in the leaves to every other part of the plant. 3. Destroying it therefore halts that movement of food, which is why ring-barking eventually kills a tree. 4. Water and dissolved mineral salts are absorbed by root hairs and carried upward in the xylem, which is untouched. 5. Oxygen enters and leaves the leaf by diffusion through the stomata, so it needs no transport tissue at all. _Source: NECTA CSEE 2021 Biology 033, Question 1: Multiple Choice, item (x)_
