Which term is defined as a group of similar cells performing a specific function?

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

Answer: (B)

Grouping similar cells that work together to perform a common function is tissue. It sits between a single cell and larger structures: tissues form organs, and organs combine into organ systems. A cell on its own is a single unit, not a group. An organ is made of different tissues coordinating to carry out a task, like the stomach with its muscle, lining, and glandular tissues. A system is a collection of multiple organs functioning together, such as the digestive system. So tissue is the right term because it specifically describes a cohesive group of like cells carrying out a shared role.
