Why do multicellular organisms contain specialized cells? 2. Give two examples of specialized cells and explain the cell's unique role in the human body. Identifying Structures On the lines provided, place the following terms in order from smallest to largest level of organization. 3. tissues 4. organ systems 5. organs 6. individual cells Reviewing Key Skills 7. Comparing and Contrasting Compare the activities of a specialized cell in a multicellular organism to those of a unicellular organism. 8. Using Analogies The specialized cells in a multicellular organism have unique roles to play. Create an analogy that describes a situation in which specific organisms or objects have unique roles in a system. 9. Applying Concepts Is your tongue a tissue, an organ, or an organ system? Explain your answer. 10. Comparing and Contrasting How are tissues and organs different?
