Which is the primary constituent of a coccolith?
The primary constituent of coccoliths is calcium carbonate, or chalk. Calcium carbonate is transparent, so the organisms’ photosynthetic activity is not compromised by encapsulation in a coccosphere. Coccoliths are produced by a biomineralization process known as coccolithogenesis.
How are coccolithophorids different from other microfossils?
Coccolithophorids are distinguished by special calcium carbonate plates (or scales) of uncertain function called coccoliths, which are also important microfossils. However, there are Prymnesiophyceae species lacking coccoliths (e.g. in genus Prymnesium ), so not every member of Prymnesiophyceae is a coccolithophorid.
When does the calcification of coccolithophore take place?
Generally, calcification of coccoliths occurs in the presence of light, and these scales are produced much more during the exponential phase of growth than the stationary phase. Although not yet entirely understood, the biomineralization process is tightly regulated by calcium signaling.
What are the functions of the Coccolith appendages?
Coccolith appendages have also been proposed to serve several functions, such as inhibiting grazing by zooplankton. Coccoliths are the main component of the Chalk, a Late Cretaceous rock formation which outcrops widely in southern England and forms the White Cliffs of Dover, and of other similar rocks in many other parts of the world.
