Bacterial Cytoplasmic Membrane | Components, Structure & Function. He has a master's degree in science education. According to the way they obtain energy, bacteria are classified as heterotrophs or autotrophs. They are unique because they require high levels of salt that would be lethal to most organisms. These organelles are responsible for a variety of cellular functions, such as obtaining nutrients, producing energy, and making proteins. They can be archaea, bacteria, or eukaryotes. It is believed that cyanobacteria are the origins of green land plants. There are many organisms that live in conditions that we would consider inhospitable. Others are capable of producing acidic proteins that increase solvation and thereby improve function in high salinity.2 This adaptation is restricted to the extremely halophilic archaeal family Halobacteriaceae, the moderately halophilic bacterial order Halanaerobiales, and the extremely halophilic bacterium Salinibacter ruber. They can be divided into six major types: bacteria, archaea, fungi, protozoa, algae, and viruses. subcellular structures are specialized to perform certain functions, which are different from the functions performed by other subcellular structures.
