Artefacts are features of the specimen that may be caused by the preparation process.Artefacts are damage caused in specimen preparation and can be confused with specimen ultrastructure.An example of this is bacterial mesosomes which were invaginations of the cell membrane.Initially they were thought to have a particular function, but scientists realised they were artefacts as they were no longer visible when more advanced preparation techniques were used.
