Xylem tissue is responsible for transporting water and minerals from the roots to the rest of the plant. Phloem tissue, on the other hand, is involved in transporting nutrients, such as sugars and amino acids, produced in the leaves to other parts of the plant. Essentially, xylem moves materials upward, while phloem moves them both upward and downward.
In Biology, structure of things is related to function. Xylem serves to transport water from the roots up through the shoots and the rest of the plant. Since water is more important to living things than food is, it makes sense that its structure is a larger diameter. It also explains why xylem cells are located toward the center of a stem- it is a more protected location in case of adverse temperatures, predators or mechanical injury.
Phloem serves to transport food/carbs either up or down, depending on where they are made (source) and where they are needed (sink), and although phloem also transports a certain amount of water, it is just so that the food molecules are solubilized.
The difference between xylem and phloem is functional as well as structural.
1. xylem is used for conduction of water and minerals whereas phloem is used for conduction of prepared organic food material.
2. Xylem consists of trachieds, vessels (only in angiosperms) and xylem parenchyma,
whereas phloem consists of sieve tubes, companion cells (only in angiosperms) and phloem parenchyma.
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
The vascular cambium is the tissue responsible for forming secondary xylem and phloem in terrestrial perennial plants. It is a meristematic tissue located between the primary xylem and primary phloem in the vascular bundles. The vascular cambium undergoes cell divisions to produce new cells that differentiate into secondary xylem towards the inside and secondary phloem towards the outside, contributing to the growth of the plant.
the cells of phloem are the only ones with cytoplasm
The vascular cambium tissue makes xylem and phloem.
The two types of vascular tissue are xylem and phloem. Xylem is responsible for transporting water and minerals from the roots to the rest of the plant, while phloem transports sugars and other nutrients produced by the plant through photosynthesis to different parts of the plant.
The dark center of a stem or root that is dead
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.

I believe it is the vascular cambium layer, not %100
