The structure above the cellular level is called a tissue. Tissues are groups of similar cells that work together to perform specific functions in the body. Examples of tissues include muscle tissue, nervous tissue, and connective tissue. Tissues are organized into organs, which are then organized into organ systems, ultimately making up the body. To find the answer to this question, you would need a basic understanding of human anatomy and biology, or you could conduct a quick internet search using keywords such as "structural levels of organization in the body" or "what is above the cellular level in the body."
