Prokaryotic Cell: Definition, Characteristics, Diagram & Structure must be adapted to high salt levels, whereas in the compatible solute adaptation, little or no adjustment is required to intracellular macromolecules; in fact, the compatible solutes often act as more general stress protectants, as well as just osmoprotectants.[3]. ______ is a special type of bacteria that performs photosynthesis. Halobacteriaceae is a family that includes a large part of halophilic archaea. -. The organisms grow in extreme salt environments and thus are called halophiles, or salt-loving. For example, muscle cells have more mitochondria than most other cells so that they can readily produce energy for movement; cells of the pancreas need to produce many proteins and have more ribosomes and rough endoplasmic reticula to meet this demand. These multicellular eukaryotes depend on plants and other organisms for nutrition. This is seen in cases such as the genus Haloarcula, which is estimated to make up less than 0.1% of the in situ community,[9] but commonly appears in isolation studies.
