What are tissues made up of?

• A. Single cells with unique functions
• B. Groups of cells with a common structure and function
• C. Only muscle cells
• D. Only nerve cells

Answer: (B)

Tissues are composed of groups of cells that share a common structure and function. This organization allows the cells to work together to perform specific activities and roles within the body. For example, muscle tissue is made up of muscle cells that contract to facilitate movement, while epithelial tissue is composed of cells that cover and protect surfaces. The classification of tissues into types, such as connective, epithelial, muscle, and nervous tissue, further illustrates how the cells collaborate to fulfill bodily needs. The other options, while they mention cells, do not capture the comprehensive nature of what constitutes a tissue. Individual cells or specific cell types do not define a tissue; rather, it is the collective arrangement and shared purpose of multiple cells that create the functional unit known as a tissue.
