Detailed explanation-1: -Xylem transports water, minerals, and nutrients from the soil to all the plant parts. There are two types of “transport” tissues in plants-xylem and phloem. Water and solutes are transported by the xylem from the roots to the leaves, and food is transported from the leaves to the rest of the plant by the phloem.

Detailed explanation-2: -The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves.

Detailed explanation-3: -Xylem transports water in plants. Water is absorbed from the soil through root hair cells. Water moves by osmosis from root cell to root cell until it reaches the xylem. It is transported through the xylem vessels up the stem to the leaves.

Detailed explanation-4: -The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients. The word xylem is derived from the Ancient Greek word (xylon), meaning “wood"; the best-known xylem tissue is wood, though it is found throughout a plant.
