diatoms and dinoflagellates

• Diatoms and dinoflagellates are classified in domain Eukarya and kingdom Protista
• Diatoms are classified in the phylum chrysophyta
• Dinoflagellates move through the ocean with the help of two flagella
• Diatoms move through the ocean using the movement of tides and currents only
• Dinoflagellates are classified in phylum pyrrophyta, which means red algae
• Diatoms and Dinoflagellates are both producers
• Dinoflagellates can have an eyespot that is sensitive to light
• Diatoms have a cell wall made of silica, a transparent glassy substance
• Dinoflagellates have a cell wall made of cellulose
• Round Diatoms are considered to be Centric Diatoms
• Diatoms reproduce both sexually and asexually
• Diatom cell walls have two halves called Frustules
• These organisms can do photosynthesis and taken food for nutrition Dinoflagellates
• These organisms sometimes have oil droplets to help them float closer to the surface Diatoms
• An algal bloom of these organisms is called a red tide and can cause toxins to build up in the filter feeding organisms Dinoflagellates
• An algal bloom of these organisms is called a brown tide. these can lead to low oxygen levels and fish Diatoms
• Some species of Dinoflagellates produce light when disturbed possibly as a defense mechanism Dinoflagellates
• These are the most numerous organisms in the ocean. Most organisms in the marine ecosystem rely on them Diatoms
