Critical Thinking
15. Do all organisms have cells, tissues, organs, and organ
systems? Give examples to support your answer.

have tissues, organs and organ systems. Even a unicellular organism
such as a bacterium is made of a cell. It is does not have tissues,
organs, or organ systems. More complex, multicellular organisms like
humans have cells, tissues, organs, and organ systems.
