Summary
Euglypha acanthophora and Euglypha strigosa, testate amoebae with siliceous shells, undergo binary fission producing daughter cells. The siliceous plates from which the shells are constructed are produced in the Golgi and perinuclear regions of the parent. At binary fission these pass along microtubule pathways and are manoeuvered into position in the daughter-cell by microtubule (20–25 nm) and microfilament (7–9 nm) systems. The latter in the form of adhesion plaques are instrumental in the coordination and deployment of the shell-plates.
