Examining under a a light microscope, there are characteristics that would allow for identification of the cell as an animal cell rather than a plant cell. Some common things to look for are summarized in table below:

Characteristics     Plant Cell              Animal Cell
Cell shape            Rectangular          Irregular
Outer covering     With cell wall         No cell wall but has cell membrane
Vacuoles              One and large       Many and small
Chloroplast          Green pigments    Absent
Centriole              Green organelles  Barrel-like structure

Distillation.  distillation is the correct answer.
