Biology: Protozoa and Invertebrate Lab

Purpose: ______

______

______.

Materials:

  • Living Cultures of Stentor, Euglena, Hydra, Volvox, Paramecium, Daphnia
  • Microscopes
  • Deep Well Slides
  • Medicine Droppers
  • Protoslo

Methods:

  1. Record your methods in a numbered list.
  2. The methods should be similar for each station, so after you write down your methods for the first station, you can simply write “Repeat methods for all stations” as your last step.

Data:

Station I

  1. Name of Organism: ______
  1. Draw the organism under 10x magnification?
  1. Draw the organism under 40x magnification?
  1. Write down three terms to describe the appearance of this organism.

Station II

  1. Name of Organism: ______
  1. Draw the organism under 10x magnification?
  1. Draw the organism under 40x magnification?
  1. Write down three terms to describe the appearance of this organism.

Station III

  1. Name of Organism: ______
  1. Draw the organism under 10x magnification?
  1. Draw the organism under 40x magnification?
  1. Write down three terms to describe the appearance of this organism.

Station IV

  1. Name of Organism: ______
  1. Draw the organism under 10x magnification?
  1. Draw the organism under 40x magnification?
  1. Write down three terms to describe the appearance of this organism.

Station V

  1. Name of Organism: ______
  1. Draw the organism under 10x magnification?
  1. Draw the organism under 40x magnification?
  1. Write down three terms to describe the appearance of this organism.

Station VI

  1. Name of Organism: ______
  1. Draw the organism under 10x magnification?
  1. Draw the organism under 40x magnification?
  1. Write down three terms to describe the appearance of this organism.

Analysis:

For each organism:

  1. Name of the organism: ______
  2. This organism is a(n) protozoa / invertebrate. (Circle one)
  3. This organism is plant-like / animal-like. (Circle one)
  4. Does this organism move? If so, how?
  5. How does this organism get energy? If it feeds off other organisms, briefly describe the feeding process.
  6. What are some structures that are unique to this organism?

Create 3 venn diagrams to compare and contrast:

  • Euglena with Volvox
  • Stentor with Paramecium
  • Hydra with Daphnia

Discussion:

  1. Describe three things that you learned in this lab.
  2. What are two differences between protozoa and invertebrates?
  3. What is one difficulty that you had with this lab?

Extra Credit:

  1. Complete data and analysis questions for the protozoa called Amoeba proteus.
  2. Label cellular structures of protozoa and invertebrates in your drawings.
  3. Create a cladogram, include derived characteristics, for the 6 organisms studied in this lab.
