Definition: Oligosynthetic is a scientific field that deals with the study of multicellular organisms and their cells. It is an interdisciplinary area that combines genetics, biochemistry, and molecular biology to understand how these cells grow, divide, and replicate in response to environmental stimuli. The term "oligosynthetic" refers to organisms that are genetically identical but differ in the structure or function of their cell membranes. These organisms can be found in a wide range of environments, from aquatic to terrestrial habitats
