Which term describes a structure made up of different tissues that work together to do a specific job?

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

Answer: (B)

This question tests how biological organization is put together. A tissue is a group of similar cells performing a common function. When different tissues come together in one structure to cooperate on a specific task, that structure is an organ. For example, the heart contains muscle tissue to contract, connective tissue for support, and nervous tissue to help coordinate its rhythm. All these tissues work in harmony within the heart to pump blood, which is why it’s defined as an organ. In contrast, a system is a collection of organs that collaborate to carry out broader functions (like circulation as a system), and a cell or tissue on its own doesn’t fulfill the idea of multiple tissue types working together in one structure.
