Both are vascular tissues of the vascular plant. Xylem is dead, woody tissue mostly that transports water from the roots of the plant to the leaves. Phloem is vascular tissue that transports sugars manufactured by the plant to all the areas that need such sugars.
The xylem will transport the minerals and water up the plat from the roots. The Phloem will carry the organic nutrients and sugar.
Phloem has a two-way flow
The flow is from the roots to the plant so the flow goes up.
Xylem is deeper inside the plant (near the trunk) and transports water up to the leaves. Phloem is near the outside and transports sugar and other materials all throughout the plant.Xylem has a one way flow, while phloem can go either directions.Xylem Is in the roots. Go Apex Kids -Emily
Xylem vessels are made up of dead cells with a thick, strong cell walls and have a hollow lumen that allows water to flow through them. The xylem cells form continuous tubes from the leaves down to the roots. This acts like a drinking straw and helps in the flow of water with dissolved minerals from the roots to the leaves.
Water goes up from the roots and the food goes to all parts of the plant.
Xylem is different from phloem structurally and functionally.Xylem consists of Tracheids, vessels and xylem parenchyma whereas phloem consists of Sieve tubes, companion cells and phloem parenchyma.Xylem conducts water and minerals to the leaves whereas phloem transports the prepared food from leaves to different parts of plant body.

can i get some help

I assume you are referring to the mass flow hypothesis, where water from the Xylem is diffused into the phloem, adding pressure inside of the phloem which causes the movement of materials through the plant. Any good A-level (erm...or American equivalent?) textbook will have a full description of mass flow hypothesis. I found (a long time ago :( ) when I was learning this that drawing yourself a diagram of it helps a lot. Good luck.
Water goes up from the roots and the food goes to all parts of the plant.
Yes, this facilitates the distribution of food material to all parts of the plant equally well.
The movement of sugars in the phloem begins at the source, where (a) sugars are loaded (actively transported) into a sieve tube. Loading of the phloem sets up a water potential gradient that facilitates the movement of water into the dense phloem sap from the neighboring xylem (b). As hydrostatic pressure in the phloem sieve tube increases, pressure flow begins (c), and the sap moves through the phloem by mass flow. Meanwhile, at the sink (d), incoming sugars are actively transported out of the phloem and removed as complex carbohydrates. The loss of solute produces a high water potential in the phloem, and water passes out (e), returning eventually to the xylem.
There is a layer of living Phloem and there is a layer of living xylem. Both these layer produce dead tissue, the Phloem produces bark (dead protective outer layer), the xylem produces wood (dead supportive inner layer). Both the wood and the bark are dead. It is only the two thin layers of Phloem and Xylem that are alive.
There are two types of vascular tissue in plants - the xylem and phloemXylem are elongated water conducting cells. The walls of the xylem are perforated and allow water and salts to pass though side ways from cell to cell.The walls of the xylem tissue are strengthened by deposition of lignin on them. This lignin makes the cell woody and impermeable. Xylem is the wood in woody plants that also help in supporting the plants.Phloem are living cells supported by companion cells. The end walls of these calls are perforated and allow organic solutes to flow to different parts of the plant.
