Astudent examines a cell under the microscope and determines that it is a eukaryote. all but one structure could the student come to this conclusion. which structure is of no ?

The eukaryotes are the organisms that contain the genetic material (DNA) inside the membrane enclosed nucleus. These organisms contain membrane bound cell organelles, such as mitochondria, Golgi apparatus etc. as opposed to the prokaryotic organisms  that contain no membrane bound organelles and no nucleus. The presence of enclosed nucleus and membrane bound organelles helps in determining that the cell is Eukaryote, but the presence of cell wall will be of no help as both the prokaryotes as well as eukaryotes contain cell wall.

Hence, the correct answer is 'cell wall'.
