The integrated group of cells that have a common function, structure, or both are called tissues.

Here's a breakdown:

* Function: Cells within a tissue work together to perform a specific task, contributing to the overall function of an organ.

* Structure: Cells within a tissue often have a similar shape and structure that allows them to carry out their function effectively.

Examples of Tissues:

* Epithelial tissue: Covers surfaces, lines cavities, and forms glands.

* Connective tissue: Supports and binds other tissues, including blood, bone, and cartilage.

* Muscle tissue: Responsible for movement.

* Nervous tissue: Conducts electrical impulses, allowing communication throughout the body.
