Student Exploration: Paramecium Homeostasis
Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts
in the orange boxes.
Vocabulary: adaptation, cell mouth, cilia, concentration, contractile vacuole, food vacuole, homeostasis,
hypertonic, hypotonic, macronucleus, micronucleus, oral groove, osmosis, paramecium, solute, solution,
solvent
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. The images show red blood cells (RBCs) in three different solutions.
A. Which image shows RBCs in normal blood plasma? b
B. Which image shows RBCs in pure water? c
C. Which image shows RBCs in a very salty solution? a
2. What do you think is happening in images A and C?
in A the RBCs are shrinking meaning that it is hypertonic where
the water is going out of the cells while salty solution is going in
the cell. in C the it is bursting where the cell absorbs the water
into the cell.
Gizmo Warm-up
A paramecium is a one-celled organism that lives in ponds and other bodies
of water. One of the challenges for a paramecium is to maintain astable size
and shape.
On the Paramecium Homeostasis Gizmo, turn on the Show labels
checkbox. Try to determine the function of each of the labeled structures.
1. Through which two structures do you think oval grove and the
food enters the paramecium? cell mouth.
2. Which two structures contain DNA? micronucleus and the
macronucleus
Cilia, which are
3. Which tiny structures help the paramecium
smalland hair-like
to move around?
that helps with
moving
