its a phenomenon by which different cells adhere(stick) to each other....it is possible due to a glycolipid layer called glococalyx....its due to interantigenic recognition.....it is due to cell adhesion by which cells of same type join up forming a TISSUE of a kind.....

adhesion is just how cells stick to a substrate or each other. Like, how a cell will stick to the petri dish... or how cells lining your stomach stick together and create a barrier so that your breakfast doesn't leak into your abdomal cavity.

There are several molecules that are responsible for this ... some create very tight seals (skin, stomach lining).. and some are looser (allowing fluids, gasses and cellular-messengers to pass from one cell to a neighbor)

look up biofilm, it's pretty cool if you want to know how plaque sticks to your teeth
