Detailed explanation-1: -What is present in the liquid? Solution : Starch <br> The main function of xylem is to transport water, and some soluble nutrients including minerals and inorganic ions, upwards from the roots to the rest of the plant.

Detailed explanation-2: -Xylem sap consists mainly of water and inorganic ions, although it can also contain a number of organic chemicals as well. The transport is passive, not powered by energy spent by the tracheary elements themselves, which are dead by maturity and no longer have living contents.

Detailed explanation-3: -xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.

Detailed explanation-4: -The xylem vessels and tracheids transport water and minerals from the roots to all parts of the plants.

Detailed explanation-5: -Transportation of water takes place through tracheids and vessels, the dead cells of xylem.
