<i>Coccolithus huxleyi</i>(Lohm.) Kamptn II. The flagellate cell, aberrant cell types, vegetative propagation and life cycles

Abstract

Coccolithus huxleyi propagates vegetatively by simple constriction of the cell including the cover. Possibly a sexual life cycle also exists consisting of an alternation between a coccolith-covered cell and a scaly flagellate, the structure of which is presented in this paper. Attempts at nuclear staining for determination of chromosome numbers have so far been unsuccessful.
