Xylem carries-
A
water up from the roots
B
water down from the leaves
C
Glucose from the roots
D
Glucose down the stem
Explanation: 

Detailed explanation-1: -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-2: -XYLEM. Water travels from a tree’s roots to its canopy by way of this conductive tissue. There are many different processes occuring within trees that allow them to grow. One is the movement of water and nutrients from the roots to the leaves in the canopy, or upper branches.

Detailed explanation-3: -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. They move water.

Detailed explanation-4: -Main function – upwards water transport. The xylem, vessels and tracheids of the roots, stems and leaves are interconnected to form a continuous system of water-conducting channels reaching all parts of the plants. The system transports water and soluble mineral nutrients from the roots throughout the plant.

Detailed explanation-5: -In plants, vascular tissue named xylem transports water and minerals from roots to shoots and leaves. Transportation of water takes place through tracheids and vessels, the dead cells of xylem.
