What term describes a group of tissues carrying out a common function?

• A. Symbiosis
• B. Organ
• C. Cytoplasm
• D. Diffusion

Answer: (B)

Groups of tissues that work together to perform a specific function form an organ. This is the level of organization just above tissues in the body’s structure: cells make tissues, tissues make organs, and organs can form part of organ systems. An organ is a distinct structure, like the heart, that contains several tissue types working in concert to achieve its role—pumping blood in this case. Symbiosis would describe a relationship between different organisms, not a structure inside an organism. Cytoplasm is the jelly-like material inside a cell, not a larger structure made from multiple tissues. Diffusion is the passive movement of particles from high to low concentration, a process, not a body part.
