Nucleoid: DNA in the bacterial cell is generally confined to this central region. Though it isn't bounded by a membrane, it is visibly distinct (by transmission microscopy) from the rest of the cell interior.
Bacterial Cell Structure and Function. Cellular world can be divided into two types, depending on the presence of nuclei inside cells. Eukaryotic cells have a well-defined nucleus surrounded by a nuclear envelope, whereas prokaryotic cells lack this compartment. All bacteria are prokaryotes. We will discover the structure and function of bacteria in this article. What do bacteria look like? When observing bacteria with microscope, it is not difficult to compare bacterial cell shapes and arrangements. There are many bacterial morphologies, each of them with a specific name. 1  Rod-shaped (Baccilus) i.e. Escherichia coli, Bacillus cereus. 2  Spherical (Coccus): i.e. Staphylococcus epiderminis. 3  Curved (Vibrio, Spirochaete) i.e. Vibrio cholera, Rhodospirilium rubrum. 4  Square-shaped (Arcula) 5  Star-shaped (Stella)
