 1. Classify the various protozoans.  2. Identify their means of locomotion.  3. Describe how the protozoans move.

 All of the organisms are unicellular, microscopic called protozoans  Protozoans live in a variety of habitats in bottom sediments, along substrate surfaces and within the water column  PROTOZOANS are CLASSIFIED in kingdom Protista and phylum protozoa  The protozoa are divided into 3 classes based on their means of locomotion: 1. ciliates 2. ameboids 3. flagellates  GUESS THE AIM????

 ACTIVITY SHEET- label diagrams  GROUP ACTIVITY: WRITE ON BOARD, draw and classify kingdom, phylum, class and an example  Each group answer the key question: HOW DO PROTOZOANS MOVE ABOUT? A. CILIATES  B. FLAGELLATES  C. AMEBAS groupdrawclassifyMethod of movement ciliates flagellates ameboids

 CILIATES-beating of CILIA(microscopic hairs) in unison  FLAGELLATES-have 2 whiplike tails called FLAGELLA to move  AMEBAS-live on surface of substrates and move by means of a cytoplasmic extension(called ameboid movement) into extensions of their cell called PSEUDOPODS(false feet)

 The protozoans are grouped into 3 different classes, based on their means of locomotion. These are the ciliates, the flagellates and the ameboids. Protozoa include marine and freshwater species.

 1.True or false. Correct for full credit This organism is an ameba.  2. Describe the different structures used in movement in the euglena, dinoflagellate and paramecium.  3. Which organism uses pseudopods or cytoplasmic extensions to move and ingest food. A. ameba B. paramecium C. diatom D. Euglena E. Noctiluca
