Which structure transports water from the roots to the rest of the plant?
A
xylem
B
phloem
C
stem
D
leaf
Explanation: 

Detailed explanation-1: -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: -xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support.

Detailed explanation-3: -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-4: -Continuous transpiration occurring in all of the leaves of a plant creates a negative pressure in the water column (xylem). This exerts an upward pull on the water column, called transpiration pull. And thus, the water present in the xylem column transports up to the tip of the stem, leaves, etc.
