Sticking Together

What does it mean to be multicellular? One answer is that an organism is multicellular when two or more neighboring cells not only stick together but interact and communicate. Some prokaryotic species have cells that stick together, but these cells act independently. Only eukaryotic cells have evolved true multicellularity. In this module we will learn about some of the advantages of sticking together and interacting. We will also explore some ideas about how multicellularity might have originally evolved.
