 Protozoans  Heterotrophic (Obtain food from other organisms)  Four

 A pseudopod is a temporary bulge of the cell membrane filled with cytoplasm  It is used for feeding and movement  Another Name: Sarcodines  A member of this group: Ameoba

 Hair-like projections that move in a wavelike pattern. It is used for movement, feeding, and to sense the environment.  The large nucleus controls the everyday tasks and the small nucleus functions in reproduction.  Ciliates is another name  Paramecium are a common member.

 A flagellum is a long, whip-like structure that is used for movement  Zooflagellates have one to eight long, whip- like flagella to help them move. They live inside the bodies of other organisms.  Symbiosis: A close relationship between two species where at least one species benefits.

 Move  The way they LIVE and MOVE  Sporozoan: Parasites that feed on the cells and body fluids of their hosts.

 Get their food from their environment  Heterotrophs  Fungus; move

 Water Molds  Water or moist places  They grow as tiny threads that look like a fuzzy covering on a living organism

 Slime Molds  In moist soil and on decaying plants and trees  When food is scarce, they will creep together and form a multicellular mass  They move in an amoeba-like way by forming pseudopods and oozing along the surfaces of decaying material.  Spore: Tiny cell that can grow into a new organism

 Algae  Chloroplasts; sun  Autotrophs (make their own food)

Euglenoids  No Cell Wall  Unicellular  Use a flagella for movement  They are unique because when sunlight isn’t available, they become heterotrophic and EAT.

 Dinoflagellates  Bodies are covered by stiff plates  They live in the water  Have two flagella and contain chlorophyll as well as other pigments  Random fact: They can glow in the dark!

 Diatoms are unicellular with glass-like cell walls.  They move by shooting chemicals out of their cell walls. This gives them a kind of jet propulsion.

 Green algae  Where do they live? Freshwater, saltwater, at the bases of trees/in moist soil  Most are unicellular, some form colonies, and a few are multicellular

 Red algae  They are multicellular SEAWEEDS  Their red color is beneficial because: They can live deep below the ocean’s surface The red pigment is good at absorbing a small amount of light.

 Brown algae  A pigment is a chemical that produces color  In the Pacific coastal waters, brown algae makes the GIANT KELP.

 An organism that has the ability to make its own food.

1. Define heterotroph and autotroph. Give an example of each. 2. Describe how protists are different from animals, plants, and fungus. 3. Explain the difference between unicellular and multicellular. 4. What are the three concepts of the cell theory. Spore: tiny cell that can grow into a new organism

 A heterotroph cannot make its own food, so it has to get it from another organism.  An autotroph can make its own food.  Examples:  Heterotroph: Animals or Fungus  Autotroph: Plants

 Protists are much simpler than plants, animals, and fungus.  They are typically unicellular, while plants, animals, and fungus are multicellular.

 Unicellular: A single celled organism  Multicellular: Many cells make up one organism

 Every living thing is made up of one or more cells.  Cells carry out the functions needed to support life  Cells come only from other living cells

 Heterotrophic  Able to move from place to place

 Heterotrophic  Cell Walls  Reproduce with spores

 Autotrophic
