Bacteria, which are spherical or ovoid in shape, are called âcoccusâ (plural: cocci) (Figure 2.2). Based on the arrangement of the cells they are of the following types. (a) Coccus: The spherical bacteria cells, called cocci, are present as single individuals. (b) Diplococcus: The cocci are arranged in pairs. (c) Streptococcus: The cocci are arranged in chains, as the cells divide in one plane. (d) Tetrads: The cocci are arranged in packets of four cells, as the cells divide in two plains. (e) Staphylococcus: The cocci are arranged in grape-like clusters formed by irregular cell divisions in three plains.
