“ WHAT IS THE KINGDOM PROTISTA? ” Matthew Robbins Mrs. Brown 12/5/08
2
“ WORDS YOU DON’T KNOW ” The words you don’t know are called Protozoan, Pseudopod, Cilium & Trypanosomes.
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 different phyla 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 cilia for 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.
