Which term describes a group of similar cells performing a common function?

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

Answer: (D)

A tissue is a group of similar cells organized to perform a specific function. This grouping allows those cells to coordinate and carry out tasks efficiently; for example, muscle tissue is made of muscle cells that contract together to move a part of the body, while epithelial tissue lines surfaces and protects them. Tissues come together to form organs, like the heart or stomach, and organs then work within organ systems to carry out the body's overall functions. A single cell is just one unit, not a group. An organ is made up of multiple tissues, and a system is made up of multiple organs. So the idea of a group of similar cells working as a unit to accomplish a shared job corresponds to tissue.
