A group of tissues working together to perform a function is a ___.

Explanation:
Understanding levels of organization in the body helps here: tissues join to form organs, and organs assemble into organ systems. A group of tissues working together to perform a specific function is an organ, because the tissues coordinate within one structure to carry out that task. For instance, the heart relies on muscle tissue, connective tissue, and lining to pump blood as a single unit. An organ system, by contrast, is made up of multiple organs working together to accomplish a broader set of functions, like the circulatory or digestive systems. So the correct term for a unit formed by tissues acting together is organ.
