What is a group of cells that function together known as?

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

Answer: (B)

A group of cells that function together is known as tissue. In biological terms, tissues are collections of similar cells that work together to perform a specific function. For example, muscle tissue is made up of muscle cells that enable movement, while nervous tissue consists of neurons that transmit signals throughout the body. Understanding the concept of tissue is foundational in biology, as it helps in recognizing how various cells cooperate to form more complex structures, such as organs. Organs, in turn, are composed of different types of tissues that work collaboratively to perform broader functions. The other terms mentioned—organ, system, and cell—do not accurately describe a grouping of cells functioning together. An organ is made up of different tissues, a system is a higher level of organization composed of multiple organs, and a cell is the basic unit of life, not a group.
