Step 1: Understand the hierarchy of biological organization in the human body. The levels of organization include cells, tissues, organs, organ systems, and the organism as a whole.
Step 2: Recall the definition of a tissue. A tissue is a group of similar cells that work together to perform a specific function. Examples include muscle tissue, nervous tissue, and epithelial tissue.
Step 3: Differentiate between the other options: a cell is the basic unit of life, an organ is a structure made up of multiple tissues working together, and an organ system is a group of organs that perform a collective function.
Step 4: Match the definition provided in the question ('groups of many cells working together to perform a common function') with the correct term from the options.
Step 5: Conclude that the correct answer is the term that aligns with the definition of a tissue, as it fits the description provided in the question.
