THE FINE STRUCTURE OF HYMENOMONAS (CRICOSPHAERA) CARTERAE. II. OBSERVATIONS ON SCALE AND COCCOLITH PRODUCTION.

Abstract:

:The fine structure of the marine coccolithophorid Hymenomonas (Cricosphaera) carterae (Braarud & Fagerland) Manton & Peterfi is reported. Details of the formation of the circular organic body scales are presented. Their formation is shown to be closely linked with the presence of tubules found within the Golgi cisternae. The details of coccolith production are also discussed. The formation of the organic matrix scale appears to be associated with a densely staining organelle, the intracellular coccolith pre-cursor. The precise mechanisms involved in the mineralization of the organic matrix scale is not known but 2 possibilities are discussed. The production of coccoliths in H. carterae is compared with coccolith production in other coccolithophorids that have been investigated finestructurally.
