What term describes groups of cells with similar structure and function?

• A. Cells
• B. Organs
• C. Tissues
• D. Systems

Answer: (C)

Groups of cells with similar structure and function are called tissues. This happens when cells of the same type organize together to carry out a common job—like muscle tissue contracting or nerve tissue transmitting signals. The cells in a tissue share features that suit that specific role, making the tissue a coordinated unit. An organ, by contrast, is built from different tissues working together to perform a broader function, such as the heart having muscle, connective, and nerve tissues. A system is a collection of organs that collaborate to achieve even larger tasks. Therefore, the description fits tissues best.
