The Bacterial cell Bacteria(sing. Bacterium) are microscopic, single-celled organisms that found in diverse environments. That means these organisms can live in soil, the ocean and inside the human gut. Humans' relationship with bacteria is complex. Sometimes bacteria serve as a helping hand, such as by curdling milk into yogurt or helping with our digestion. In other cases, bacteria are destructive, because they cause many diseases like pneumonia and others. Structure Bacteria (singular: bacterium) are classified as prokaryotes, which are single-celled organisms with a simple internal structure that lacks a nucleus, and contains DNA that either floats freely in a twisted, thread-like mass called the nucleoid, or in separate, circular pieces called plasmids. Ribosomes are the spherical units in the bacterial cell where proteins are assembled from individual amino acids using the information encoded in ribosomal RNA. Bacterial cells are generally surro...
