  1. “ WHAT IS THE KINGDOM PROTISTA? ” Matthew Robbins Mrs. Brown 12/5/08

  2. “ WORDS YOU DON’T KNOW ” • The words you may not know are: • Protozoan - one-celled animal-like protist. • Pseudopod - fingerlike extension of cytoplasm. • Cilium - tiny hairlike structures. • Trypanosomes - disease causing protozoan.

  3. “ KINGDOM PROTISTA ” • Kingdom Protista or Protist Kingdom is made up of very simple organisms. • A few kinds of protists are muticellular. • The protist kingdom is divided into three large groups. • These groups are made up of many differentphyla of organisms.

  4. “ WHAT ARE TWO CHARACTERISTICS OF PROTISTS? ” • Most protists are unicellular. • The protist kingdom is divided into 3 large groups.

  5. “ ANIMAL-LIKE PROTISTS ” • Protozoans are one-celled or unicellular organisms. • They often are called the animal-like protists because they cannot make their own food. • Most protozoans can move about on their own.

  6. “ NAME THREE ANIMAL-LIKE PROTISTS? ” • Amoebas, Paramecia & Trypanosomes are all examples of animal-like protists.

  7. “ AMOEBA ” • An amoeba is a protozoan. • Most amoebas live in fresh water. • They have fingerlike projections of cytoplasm called Pseudopods. • When the amoeba approaches a food particle its pseudopods surrounds the particle & form a food vacuole around it.

  8. “ HOW ARE PSEUDOPODS BENEFICIAL TO THE AMOEBA? ” • An amoeba uses its pseudopods to move through water & to trap & take in food.

  9. “ PARAMECIUM ” • A paramecium is a slipper shaped protozoans. • Cilia are tiny hair-like structures that move. • The cilia moves back & forth like tiny oars. • The beating of cilia moves a paramecium through water. • When the paramecium finds food the moving cilia create a current in the water.

  10. “ WHAT STRUCTURES DOES A PARAMECIUM USE TO MOVE? ” • It is part of a phylum of protozoa that uses ciliafor movement.

  11. “ TRYPANOSOMES ” • A trypanosome is a disease causing protozoan. • Trypanosomes also cause diseases in horses & cattle. • Trypanosomes are part of a group of protozoa with flagella. • The common name for this group is the flagellates. • Some flagellates have one flagellum & others have two or more flagella.

  12. “ HOW DO FLAGELLATES MOVE ? ” • They use a flagella to move.

  13. “ QUESTIONS ” • Protozoans algee & slime molds are all classified in the Protist Kingdom. • Amoebas move by extending their Pseudopod. • A paramecium moves by beating the Cilia that extend from its surface. • Protozoa with flagella are called Paramecium. • Sleeping sickness is caused by a Trypanosomes.
