Scribe Post: Thursday 2/16

Today in class we did a protist lab!

Homework:

1. finish UP p. 27-31

2. Read CH 15 - protists

3. Read and prep for UP p. 39-40 & 41-43 labs

4. Nature due 3/2

Lab:

Background Info on Protists:

-one-celled organisms

-found in a variety of habitats

-specialized

-some are autotrophic (need light for photo synthesis)

-some are heterotrophic (depend on autotrophs for food)

*Psuedopods use small extensions in their cytoplasm called pseudopodia to move, similar to feet*

*Flagellates have a tail to move

backward and forward*

*Ciliates have more precise

movement by using ciliates*

FILL OUT THE CHARTS OF THE AMOEBA, PARAMECIUM, AND EUGLENA

Procedure:

1. Obtain a prepared or ready-slide of Amoeba Paramecium, or Euglena.

***For our lab, we also looked at slides of Stentor, Algae, and Volvox.

2. Use low power to locate the protists, and to observe their movement.

3. Use high power to clearly observe a single organism. Experiment with different settings of the diaphragm to enhance various aspects of the organism.

4. As you observe the protists fill in the general shape, overall color, and structure used for movement in the data table.

5. Be sure to observe all 3 protist organisms.

6. Clean-up your work area and wash your hands before leaving the lab

We analyzed the following characteristics of Amoeba, Paramecium, Euglena, Stentor, Algae, and Volvox:

-General Shape

-Overall Color

-Structure for Movement

-Autotroph/Heterotroph/Both

-How do they obtain food?

-Detailed sketch!!

Stentor: Algae: Volvox:
