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 a stable 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 food enters
the paramecium? _____________________________
2. Which two structures contain DNA? ____________________________________________
3. Which tiny structures help the paramecium to move around? _________________________
4. Which structure pumps out excess water and wastes? ______________________________
B
C
A
In image A and C H2O
is either leaving or entering the red blood cells. This makes the red blood cells
hypertonic like in image A. Or hypotonic, like in image C.
The oval grove and cell mouth
The micronucleus and the macronucleus
Cilia
The contractile vacuole
