Instructions: Answer questions #1 and #2 BEFORE you run the experiment. 1. Click the top of the purple dropper on the left (P. caudatum) and drag to test tube 1 2. Click the top of the purple dropper on the right (P. aurelia) and drag to test 2 3. Click the top of each purple and drag to test tube3 4. Click on the microscope.
Oct 02, 2018 · 1. What are the objectives for this experiment? (you can summarize) The purpose is to experiment and grow two species of Paramecium and then. The purpose is to experiment and grow two species of Paramecium and then. 2. Make a hypothesis about how you think the two species of Paramecium will grow alone and how they will grow when they are grown …
May 03, 2020 · 8. Explain how this experiment demonstrates that no two species can occupy the same niche. This experiment demonstrates that no two species can occupy the same niche because when Paramecium aurelia and Paramecium caudatum were mixed, Paramecium caudatum died.
A paramecium is unicellular and moves by using cilia. Cilia are short, hair-like structures that are found on the surface of the organism. Cilia have three uses: 1.movement, 2.capturing food, 3. sensing the environment. When you observe the paramecium it may look like it only has cilia on part of its cell. In fact, the entire cell is covered in cilia!

The small nucleus only controls reproduction. Paramecium can reproduce in two ways: asexually through binary fission and sexually through conjugation. In our bacteria unit we learned what binary fission and conjugation are.
As you already learned, the cilia have three functions: to help the paramecium move, to help it capture food, and to help it sense the environment. Also on the surface you will find an indentation called the oral groove. The oral grove is lined with cilia to help the organism capture food.
The same processes are true for paramecium. In binary fission, the cell splits in two and each cell receives the same copy of DNA from the parent cell. In conjugation, the paramecium shares genetic material with another paramecium before splitting.
In the previous lab (online or in class) you observed a type or protist called a protozoan. Recall that protozoans are animal-like protists. That is, they have similar characteristics to animals. Mainly, they are heterotrophs and they must hunt for their food. Recall that protozoans can be classified by how they move.
What appears to be the cell membrane is actually a part called the pellicle. The pellicle is a stiff, outer covering that helps give the paramecium its shape. Unlike the amoeba, the paramecium is not able to change shapes (although it can bend and twist). Just below the pellicle you will find the cell membrane.
