Transform Plate Boundaries are locations where two plates slide past one another. The fracture zone that forms a transform plate boundary is known as a transform fault. Most transform faults are found in the ocean basin and connect offsets in the mid-ocean ridges.
Cell shape and Arrangement-The three main shapes of bacterial cells are: ï· Spheres (cocci [plural] or coccus [singular] ï· Rods (bacilli [plural] or bacillus [singular] ï· Helical (spirilla [plural] or spirillum [singular] The main arrangements are single cells, diplo- (pairs), staphylo- (clusters), and strepto- (chains).
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.
