Detailed explanation-1: -The xylem of a plant is the system of cellular tubes that circulates water and dissolved minerals.

Detailed explanation-2: -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-3: -The type of vascular tissue that transports water and minerals in plants from roots to leaves is phloem.

Detailed explanation-4: -The most distinctive xylem cells are the long tracheary elements that transport water. Tracheids and vessel elements are distinguished by their shape; vessel elements are shorter, and are connected together into long tubes that are called vessels.

Detailed explanation-5: -Root hairs. Single celled and large surface area, perfect for absorption of water and nutrients! Root hairs are long, thin, single cell extensions from the epidermis. They profoundly increase the overall root surface area and connection with the soil and are responsible for absorbing water and mineral nutrients.
