When viewed under light microscope, most bacteria appear in variations of three major shapes: the rod (bacillus), the sphere (coccus) and the spiral type (vibrio) Bacteria Definition. Bacteria are single-celled microorganisms with prokaryotic cells, which are single cells that do not have organelles or a true nucleus and are less complex than eukaryotic cells. Bacteria with a capital B refers to the domain Bacteria, one of the three domains of life. The other two domains of life are. The three most common bacterial cell shapes are cocci (spherical, from the Greek word for seed/berry), bacilli (rod-shaped, from the Greek word for staff), and spirilla (curved shape, from spiral). There are various ways of subdividing these three overarching shapes mostly based on how they are arranged into multicellular. There are many examples of bacteria such as chlamydia and salmonella which are microscopic one-celled organisms. Bacteria are classified into three categories according to their shapes.
