Your task is to document her care. It is a member of the domain Archaea and is found in bodies of water with extremely high concentrations of salt. This means they are all composed of one cell and do not have a nucleus or membrane-bound organelles in the cells. It takes in food from the water and digests it in organelles known as food vacuoles. - The cell membrane in archaea does not have phospholipids (fatty acids). What are sporangium? environments of bacteria In bacteria: Salt and water environments and are thus called halophiles. Most halophiles are unable to survive outside their high-salt native environments. This makes these ancient bacteria very significant in a modern world. Monera consists of unicellular prokaryotes.

Microorganisms are beneficial in producing oxygen, decomposing organic material, providing nutrients for plants, and maintaining human health, but some can be pathogenic and cause diseases in plants and humans. Bacteria are unicellular organisms. The genus Halobacterium ("salt" or "ocean bacterium") consists of several species of Archaea with an aerobic metabolism which requires an environment with a high concentration of salt; many of their proteins will not function in low-salt environments. They can be archaea, bacteria, or eukaryotes. Her BP is 170/90, and she has slight pedal edema. The unicellular algae are mostly plant-like autotrophs that can make their own food.

Microbial Factories: Using Bacteria to Make Specific Compounds. However, all unicellular bacteria have a multicellular period in their life cycle. Cells function differently in unicellular and multicellular organisms, but in every organism, each cell has specialized cell structures, or organelles, of which there are many. At the protein level, the halophilic species are characterized by low hydrophobicity, an overrepresentation of acidic residues, underrepresentation of Cys, lower propensities for helix formation, and higher propensities for coil structure. When shellfish eat this algae, the poison becomes concentrated in their bodies.
