Protists Lab Name:______________________________________

For this lab, you are to

1) complete the written component of the lab,

2) find and photograph at least 6 protists per individual.

You must image the living euglena, amoebas, paramecium and stentor.

The images should be saved under the name of the protist and put in a folder under your name and hour.

They should be saved in a folder under ‘AP Biology’/ ‘Protists’

   2. Ciliated Protozoans

      Cilia:

      What is osmotic pressure?

       

       

       

      If a contractile vacuole is actively working, how would you characterize the water in which the ciliate is living (isotonic, hypertonic, hypotonic)?

       

       

       

       

      How do ciliates reproduce?

       

       

       

      Focus a prepared slide of Paramecium caudatum and draw the organism below.

      Label all structures you are able to recognize (reference page 378).

      The giant kelp beds look like they are made of plants (look like stems, leaves, etc).

      Why do some biologists not consider kelp to be true ‘plants’?
