Detailed explanation-1: -Xylem vessels carry water and minerals from the roots to the leaves. Phloem tubes carry sugar & other organic nutrients made by the plant from the leaves to the rest of the plant.

Detailed explanation-2: -The xylem transports water and minerals from the roots up the plant stem and into the leaves. In a mature flowering plant or tree, most of the cells that make up the xylem are specialised cells called vessels.

Detailed explanation-3: -xylem tracheids. The xylem tracheary elements consist of cells known as tracheids and vessel members, both of which are typically narrow, hollow, and elongated. Tracheids are less specialized than the vessel members and are the only type of water-conducting cells in most gymnosperms and seedless vascular plants.

Detailed explanation-4: -Stems carry water and nutrients taken up by the roots to the leaves. Then the food produced by the leaves moves to other parts of the plant. The cells that do this work are called the xylem cells.

Detailed explanation-5: -Xylem is one of the two types of transport tissue in vascular plants, the other being phloem. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients.
