FIG. 4.

There are two main types of reformable bonds. One type is a sticky extracellular matrix that surrounds the cells. A second type is a surface-binding protein that can interact with proteins on the surface of another cell. The upper two experimental images are (i) an electron micrograph of a biofilm of Staphylococcus aureus bacteria on a catheter and (ii) a scanning electron micrograph of a multicellular colony of C. reinhardtii, adapted from Herron et al., Sci.
