1. Coccus (def) The cocci are spherical or oval bacteria having one of several distinct arrangements (see Fig. 1) based on their planes of division. a. Division in one plane produces either a diplococcus or streptococcus arrangement.diplococcus: cocci arranged in pairs (see Fig.undamental Statements for this Learning Object: 1. There are three basic shapes of bacteria: coccus, bacillus, and spiral. 2. Based on planes of division, the coccus shape can appear in several distinct arrangements: diplococcus, streptococcus, tetrad, sarcina, and staphylococcus. 3.
