What term describes a group of similar cells that perform the same function?

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

Answer: (A)

Grouping similar cells that carry out the same job forms tissue. This arrangement lets cells specialize and work together to perform a specific function, such as muscle tissue enabling movement or nerve tissue sending signals. A single cell is just one unit, so it isn’t tissue. An organ is made up of different tissues working together to perform a broader task (like the heart), and an organ system is a collection of organs coordinating to carry out complex body functions (like the circulatory system). So the term that describes a group of similar cells that perform the same function is tissue.
