Derek was observing a specimen using a microscope. He observed a single cell on the slide. He noticed it was round in shape, with a nucleus in the middle of the cell, and a structure that the cell could use to move around. Derek concluded he was looking at an animal cell. His lab partner James disagreed and insisted that they were observing a unicellular protist. Who is correct, and which piece of evidence supports the correct claim?

James is correct; the cell has a structure that allows it to move independently.

The presence of a structure for movement, such as a flagellum or cilium, is indicative of many unicellular protists. While the cell being round and having a nucleus and cell membrane are features of both animal cells and some protists, the observed capability for independent movement is more characteristic of protists.
