What do we call a group of the same kind of cells working together?

1. Tissue

2. Organ

3. System

4. Cell

The correct answer is: Tissue

The term that refers to a group of the same kind of cells working together is 'tissue.' In biological terms, tissue is defined as a collection of cells that share a common structure and function. These cells cooperate to perform specific tasks within an organism. For instance, muscle tissue is made up of muscle cells that work together to facilitate movement, while epithelial tissue forms protective layers on surfaces and cavities. Understanding the concept of tissue is fundamental in the study of anatomy and physiology, as it bridges the gap between individual cells and more complex structures like organs and systems. Other terms provided focus on different biological organization levels. For example, an 'organ' refers to a structure composed of two or more types of tissue that work together for specific functions, while a 'system' includes multiple organs collaborating to perform broader functions within the body. A 'cell,' on the other hand, is the basic unit of life, which does not encapsulate the idea of multiple cells working together towards a common goal. This distinction highlights the unique role of tissue in the hierarchy of biological organization.
