              A student cut a section through a plant, finding a group of long, microscopic structures which lacked end walls or any cell contents. 

              Which row of the table below correctly identifies the structure described in the statement above?

                identification reason
              A xylem vessels large surface area to absorb as much water by osmosis as possible 
              B root hair cells they can support the plant better without cytoplasm, mitochondria provide energy
              C root hair cells hollowed, lignified tubes to allow uninterrupted flow of water
              D xylem vessels hollowed, lignified tubes to allow uninterrupted flow of water
