WebA cell wall, not just of bacteria but for all organisms, is found outside of the cell membrane. It’s an additional layer that typically provides some strength that the cell membrane lacks, by having a semi-rigid structure. Both gram positive and gram negative cell walls contain an ingredient known as peptidoglycan (also known as murein ). WebThe chromosome, along with several proteins and RNA molecules, forms an irregularly shaped structure called the nucleoid. This sits in the cytoplasm of the bacterial cell. In addition to the chromosome, bacteria often contain plasmids – …
