Bacterial inclusions are generally defined as a distinct structure located either within the cytoplasm or periplasm of the cell. The first cells were observed and named by Robert Hooke in 1665 from slice of cork. They can range in complexity, from a simple compilation of chemicals such as crystals, to fairly complex structures that start to rival that of the eukaryotic organelles, complete with a membranous external layer.
