Shapes of bacteria cells
WebbAnother common shape of bacteria is the coccus. Cocci are spherically shaped bacteria that organize in several distinct arrangements when in groups: diplococcus, tetrad, sarcina, and staphylococcus arrangements. The diplococcus arrangement is characterized by cell division along one plane, where the bacteria will appear to form chains. WebbBacterial cells (prokaryotic cells) are structurally much simpler than eukaryotic cells and the two cell types are compared in Table 3.2. They consists of various cell surface structures, cell wall, plasma membrane, many cytoplasmic inclusions, and the bacterial chromosome (nucleoid). Except some, all structures do not occur in every genus.
