There is structural difference between xylem and phloem. This is because their function is also different. Had there been no difference in structure, how these could have performed different function?
The layer between the xylem and phloem is called the cambium. The cambium is a type of meristem tissue that is responsible for producing new xylem and phloem cells, contributing to the growth of the plant.
The precambium is a layer of meristematic tissue found between the primary xylem and phloem in vascular plants. It is responsible for the production of secondary vascular tissue in the form of secondary xylem (wood) and secondary phloem.
Phloem
Xylem is part of the vascular tissue of plants, and the xylem and phloem together are grouped together as the stele (latin for 'pillar'). Xylem tissue is encased in lignin, the substance that creates the strength of wood, causing the protoplasm (living part of the cell) to die, and therefore be dead tissue; phloem is living tissue.
the cells of phloem are the only ones with cytoplasm
The vascular cambium tissue makes xylem and phloem.
Phloem and xylem are the two main types of vascular tissue found in plants. Xylem is the tissue that mainly carries water, and a few minerals, in the system. Phloem is the tissue that carries photosynthetic materials through the plant.

The tissue you are referring to is called vascular cambium. Vascular cambium is a meristematic tissue that is responsible for secondary growth in plants, producing additional xylem towards the inside and phloem towards the outside, contributing to the increase in girth of woody plants.

Yes, phloem is living tissue, xylem tends to be woody and dead.
Plant tissue/ conducting tissue
I believe it is the vascular cambium layer, not %100
