Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The Xylem transports
A
sugars
B
water
C
Either A or B
D
None of the above
Explanation: 

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: -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.

Detailed explanation-3: -The movement of water through xylem is not active but passive which is caused to transpiration pull. The root pressure is positive whereas the shoot region has negative pressure due to Transpiration. Hence water flows in accordance with its pressure gradient.
