Which term is associated with the structure and characteristics of living organisms?

The term "morphology" refers to the study of the form and structure of organisms, encompassing aspects such as shape, size, and the arrangement of various parts. This concept is fundamental in biology because it helps in understanding how the physical characteristics of an organism relate to its function, development, and evolutionary history. Through morphological studies, scientists can describe how organisms are constructed and how their structures suit their environments and roles within ecosystems.

The other terms listed relate to different biological concepts. "Motility" pertains to the ability of organisms to move, which is a functional aspect rather than a structural one. "Myology" specifically deals with the study of muscles, which is a narrower focus within the broader field of morphology. "Multipotency" refers to the potential of a stem cell to differentiate into multiple cell types, which is more related to developmental biology rather than the overall structure and characteristics of living organisms. Thus, morphology is the most encompassing term when discussing the structure and characteristics of living organisms.
