Charles Darwin Foundation Galapagos Species Checklist


Diatoms

Part of the phytoplankton, diatoms are unicellular algae that inhabit both salt- and fresh-water habitats.
All possess a cell wall made from silica that encapsulates the cell like a skeleton. This unique structure is called a frustule.

Diatoms are divided into three classes: Bacillariophyceae and Fragilariophyceae with bilateral symmetry, and Coscinodiscophyceae that are cylindrical.

The cells have yellow or light brown chloroplasts.
