What Do You Call A Group Of Cells Working Together For A Common Function?

A cell is the smallest unit of living organism in our body.  Cells consist in many parts, but they are the smallest functional unit of organic matter.  The next order consists of a group of cells the work together for a common function.  This next level is called tissue.  Organs consist of groups of tissues and a system consists of organs that had the same general purpose, but which all perform a different function within that system.

Tissue is the cellular organizational unit of concern in the question.  Cells within that issue have the same origin and are the product of mitosis, or cell division.  They may not be identical, but they work together for a specific function.  Multiple tissues group together to form an organ.  The study of tissues is known as histology.  The study of disease in tissues is histopathology. 

Histology involves staining techniques of tissue of samples and the use of a standard optical microscope.  Over recent decades, the electron microscope has become the preferred method for studying tissues.  The study of histology has developed through the characterization of what is considered to be normal for certain types of tissues.  When one establishes what is normal for a certain group of tissues, then it is easy to discover what is abnormal and may indicate a disease state.

Tissues consist of layers called the basal lamina that separates it from other tissues.  This layer serves as a source of protection from secretions and absorption of fluids from other surrounding tissues.  The endothelium contains the vascular system of that tissue.  There are several types of tissues that are found in animals.  They include connective tissue, muscle tissue, nervous tissue, and epithelial tissue.  All of these different types of tissues serve a different function within the organ.

A group of cells performing together to achieve a specific function is termed a tissue.

I think you are thinking of a "consortium". It's a diverse community of microorganisms that collectively perform quite a different chemical and ecological function from that of any of the individual organisms. You find different types of consortia in industrial fermentation processes.

A tissue is a group of similar cells that work together to perform a particular function.
