Bacteria and Protist Mrs. Reich’s Science Class Did you know? • You can tell bacteria by their shape and protists (euglena, paramecium, amoeba), by the way they move and gather food. http://www.coleharbourhigh.ednet.ns.ca/library/i mages/biolog30.gif http://www.norcalblogs.com/watts/images/GeneralBacteria.jpg http://sustainabledesignupdate.com/wp-content/uploads/2007/11/bacteria.jpg http://www.infovisual.info/02/001_en.html Single Celled Organisms • Bacteria are organisms that are classified into the Moneran Kingdom. They are classified by their body shapes. http://www.alken-murray.com/MICROA.gif Types of Bacteria • Spiral Spiral-shaped bacteria are corkscrew shaped • Bacillus Rod-shaped bacteria • Coccus Round-shaped bacteria http://www.ynet.co.il/PicServer2/01082004/570748/vis350691_-coccus_wa.jpg http://www.fallingpixel.com/products/142/mains/baci1.jpg http://newsimg.bbc.co.uk/media/images/44350000/jpg/_44350357_syphilissplcred.jpg Protist • Protists are organisms that are classified into the Kingdom Protista. Although there is a lot of variety within the protists, they do share some common characteristics. Protist • Protists are usually one celled organisms that live in all moist environments. They vary in the way they obtain food and move. Examples of protists include euglena, paramecium, and amoeba. http://www.scientific-art.com/GIF%20files/Zoological/microbea.gif Euglena • A Protist with Flagella • These protists move pulling themselves with long whip like structure called flagella. • These protists can have one or more flagella that help them move. • The euglena is unique in that it has characteristics of both a plant and an animal, it contains chloroplasts that photosynthesize and also can consume other organisms as well. http://www.rkm.com.au/EUGLENA/EUGLENA-labels-600.jpg Paramecium • A Protist with Cilia • These protists move by beating tiny hair-like structures called cilia. • The cilia act as tiny oars that allow the protist to move through its watery environment. • The cilia also move and help to capture food directing in toward a groove that functions like a mouth. http://cmapspublic2.ihmc.us/rid=1228170101921_190956518_12114/paramecium.gif Amoeba • A Protist with Pseudopods • These protists move by extending their bodies forward and then pulling the rest of their bodies forward as well. • The finger-like structures that they project forward are called pseudopods (false foot like a snail). • The pseudopods are also used to trap food. movie • http://player.discoveryeducation.com/index.cf m?guidAssetId=23679F25-DC80-43ED-8A02D9E88169955C&blnFromSearch=1&productco de=US
