In vascular plants, specialized root hairs on the roots of the plant are responsible for taking up water and nutrients. the water taken up by the roots of the plant can then be transported to the rest of the plant through the plant's a. chloroplasts b. phloem tissue c. mitochondria d. xylem tissue

The answer would be xylem tissue.

XYLEM is one of the two types of transport tissue in vascular plants. Its basic function of xylem is to transport water from the roots to shoots and lastly, leaves. It also transports nutrients. The xylem transports water and minerals through the vessel elements and tracheids, which are dead at maturity. It has a primary and secondary cell wall.

The answer is "Xylem tissue (D)".
 
Xylem is a vascular plant tissue. The main role of xylem tissue is transport the absorbed water and dissolved minerals to the plant parts. This is an upward transportation and it is from plant roots to top part of the plant. Other than transportation, xylem tissue supplies the physical support to the plant.
