The tissue that transports soluble products of photosynthesis in plants is the phloem.

Here's why:

* Phloem is a vascular tissue responsible for transporting sugars (like sucrose) produced during photosynthesis from the leaves to other parts of the plant. This sugar is used for growth, respiration, and storage.

* Xylem, the other vascular tissue, transports water and dissolved minerals from the roots to the rest of the plant.
