| contractile ring t. |
a theory advanced to explain the formation of a furrow in a dividing cell. According to this theory, the gelated ring in the cortex of the dividing cell contracts (cortical gel contraction) like the nonmotile portion of an amoeba, and, therefore, decreases the surface area. Actually, however, before division the surface increases by about 26 per cent.
