Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
[Note: The purpose of these questions is to activate prior knowledge and get students thinking.
Students are not expected to know the answers to the Prior Knowledge Questions.]
1. What are some of the structures inside a cell that help it to live and perform its role in an
organism?
Answers will vary. [Students may be aware of the nucleus and plasma membrane.]
2. How do you think plant cells differ from animal cells? (Hint: What can plants do that animals
cannot?)
Answers will vary. [Students may note that plants can produce energy from sunlight, so they
must need some kind of structure for doing this.]
Gizmo Warm-up
The Cell Structure Gizmo™ allows you to look at typical
animal and plant cells under a microscope. On the ANIMAL
CELL tab, click Sample to take a sample of an animal cell.
Use the Zoom slider to see the cell at a magnification of
2000x (2000 times larger than normal). On the dropdown
menu, select Centrioles.
1. Use the up/down and left/right sliders to manipulate the
cell. Find the red arrow pointing to the centrioles. Make
a sketch of the centrioles in the space below.
2. Read the description of the centrioles. What is their function?
The centrioles help to organize the movement of chromosomes during cell division.
