Behaviour of the chrysoflagellate alga,Dinobryon divergens, during lorica formation

  • W. Herth
Article

Summary

A timed series of light micrographs illustrates the process of lorica formation inDinobryon divergens. Analysis of this series reveals that theDinobryon cell forms the lorica in two distinct phases: First, the stalk region, without rotation of the cell, and second, the vaseshaped upper part of the lorica, with five slow rotations of the cell yielding the helicoidal band structure of the lorica. Complex changes of shape by the cell body provide the model for lorica diameter.
