2. WORD BANK Paramecium- single-celled protist organism (unicellular). Oval shaped with cilia. Cilia- hair-like structures around the paramecium that help it move and get food.

3. ENDURING UNDERSTANDING The diversity of cells contributes to the diversity of life on Earth.

4. LEARNING GOAL I will observe structures and behaviors of single-celled microorganisms with a microscope. I will compare elodea cells and paramecia cells.

5. MICROSCOPIC LIFE

6. MICROORGANISMS Today we are going to look at several types of Protist organisms. I want you to pay special attention to how they are similar and how they are different.

7. AMOEBA This protist looks a lot like a blob of debris and trash. It moves much slower than a paramecium. It is easy to overlook so you need to look VERY CAREFULLY.

9. EUGLENA The first thing you will notice is the bright green color of chloroplasts inside euglena. Euglenas have a red eyespot you will see you if you get a good look. They are very fast so you need cotton to slow them down.

11. FLAGELLATES These organisms move very quickly so you need to slow them down with cotton. They can be long like cigars or round. You will notice a long hair-like structure called a flagella that they whip around to propel themselves.

13. SIMILARITIES AND DIFFERENCES How are all these protist organisms the same? How are they different?

15. WORD BANK Amoebae- single-celled protist organism. Blob and moves very slow. Euglena- single-celled protist organism. Chloroplasts and red eyespot. Flagellate- single-celled protist organism. Long hair-like structure used to propel itself.
