Bar Graph for Comparing and Contrasting
Directions:
1. Watch the video and read through the information on diatoms and dinoflagellates. 2. Type in the appropriate columns below the characteristics that apply to diatoms, dinoflagellates and the characteristics they share Characteristics of Diatoms | Similarities Between Diatoms and Dinoflagellates | Characteristics of Dinoflagellates | 1. silicate cell wall and are the most abundant type of photosynthetic organism in the ocean 2. tough outer shell(frustule) that protects the soft inside of the organism and the shape of the frustules helps scientist tell one diatom from another 3. Diatoms that have a pinnate shape display bilateral symmetry and are usually long with extensions or markings come off the diatom at right angles. Centric diatoms show radial symmetry and can be shaped like a circle, triangle or rectangle. 4. Almost all diatoms are found in the photic zone since they rely on the sun's energy. However, within the photic zone we classify diatoms as either benthic or planktonic. Benthic means they are found on the bottom (or attached to floating organisms) and planktonic means they are free-floating. Most centric diatoms are planktonic and most pennate diatoms are benthic. Diatoms are found in basically ALL aquatic environments (salt water, fresh water, cold water, warm water). | 1. single-celled organisms | 1. two flagella 2. make up the symbiotic algae that exist by living in other organisms such as coral and sea anemones 3. second most abundant primary producer in the ocean after diatoms 4. found in the ocean but some are found in sources of freshwater | 3. Use your chart to start making a deduction about the cause of the food poisoning. Based on the information you’ve gathered do you feel that the cause of the food poisoning is a diatom or a
