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

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

MICROSCOPIC LIFE

ORGANISMS Today we will observe a protist microorganism called Paramecium. Let’s look at an example of one and how to make a wet mount of this specimen.

OBSERVATIONS What movements did you observe? What did you see on the inside of the organism? What did you see on the outside of the paramecium? How big was it at 100x? At 400x? Are they living or nonliving? What is your evidence? Could you see if it was doing all of the things you have listed in your definition of a living organism? What might we do to see some of these activities?

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.
