  1. Kingdom Protista

  2. If you look at a drop of pond water under a microscope, all the "little creatures" you see swimming around areprotists.

  3. Protists are so different from each other that you can think of this kingdom as the “junk drawer kingdom.” • Protists are either plant-like, animal-like or fungus-like.

  4. Plant-like protists are autotrophs – they contain chloroplasts and make their own food. • Animal-like and fungus-like protists and areheterotrophs.

  5. Protozoansare animal-like protists(heterotrophs)grouped according to how they move. They are able to move from place to place to obtain their food. • The wordprotozoameans "little animal." They are so named because many species behave like tiny animals—specifically, they hunt and gather other microbes as food.

  6. All protozoa digest their food in stomach-like compartments called vacuoles <vac-you-ohls>. As they chow down, they make and give off nitrogen, which is an element that plants and other higher creatures can use. • Protozoa range in size from 1/5,000 to 1/50 of an inch (5 to 500 µm) in diameter. They can be classified into three general groups based on how they move.

  7. Amoebae live in water or moist places. • They feed on bacteria and smaller protists. • They have a cell membrane but no cell wall. • Amoebae ooze along by means of pseudopodia (false feet) engulfing food as they go.

  8. Giardia

  9. Protozoans with cilia have hairlike that move with a wavelike pattern. They use cilia to help them move. • They are covered with hair-like projections called cilia and they eat the other two types of protozoa as well as bacteria. • Ciliates are found in every aquatic habitat.

  10. Here is a protzoan wit flagella.

  11. Foldable • Protozoans are grouped according to how they move. • The word protozoa means “little animal” • Amoebae live in water or moist places. • Amoebae’s move with the help of pseudopodia (false feet) engulfing food as they go.

  12. Foldable • Protozoans with cilia have hairlike features that help them move. • Flagella can also help certain types of protzoan move. • If you look at a drop of pond water under a microscope you would see “little creatures” swimming around. These are protists. • They live in water but most need sunlight.
