Dinoflagellates. Dinoflagellates are the other primary form of large phytoplankton with about 2,000 species. Unlike diatoms, dinoflagellates are mobile through the use of a flagella. Also unlike diatoms, they do not have an external skeleton made of silica, however they are protected by cellulose.arine algae (seaweeds and phytoplankton) are a loose group of some of the simplest organisms that contain chlorophyll (like plants) but include members of both the Empires Prokaryota (Kingdom Bacteria-e.g., cyanobacteria) and Eukaryota (Kingdoms Chromista, Plantae and Protozoa...).
Diatoms acquired photosynthesis after the evolution of the chloroplast. Diatoms, photosynthesis protists that live in the ocean, possess strange chloroplasts with four membranes instead of two. The leading hypothesis explaining this is that the chloroplasts in diatoms actually represent eukaryotic cells that formed symbiosis with the diatoms. The inner two membranes represent the membranes of the regular chloroplasts contained in this symbiotic cell. The outer two membranes represent the plasma membraned of the symbiotic cell and the food vacuole it was trapped in.
