Which term is defined by the phrase 'a living thing'?

• A. Organ
• B. Organism
• C. Tissue
• D. Cell

Answer: (B)

The main idea here is how we name living things versus their parts. An organism is a living thing that can carry out life processes. It can be a single-celled creature like bacteria or a complex multicellular being like a human. The other terms describe parts of an organism: a cell is the basic unit of life, a tissue is a group of similar cells performing a function, and an organ is a structure made of tissues that carries out a specific job. So the phrase “a living thing” points to an organism because it refers to the whole living entity, whether it’s one cell or many cells working together.
