Do the following warm-up activity to familiarize yourself with the Gizmo before beginning.
Gizmo Warm-up
The Cell Structure Gizmo™ allows you to look at typical
animal and plant cells under a microscope. To start, click
Sample to take a sample of an animal cell. Use the Zoom
slider to see the cell at a magnification of 1000x (1000 times
larger than normal).
1. Use the up/down and left/right sliders to manipulate the
cell. Find the red arrow pointing to the centrioles.
2. Read the description of the centrioles. What is their function?
The function of centrioles is to organize the movement of chromosomes during cell
division.
Activity A:
Animal cells
Get the Gizmo ready:
Check that an Animal cell is mounted on the
microscope.
Set the Zoom to 2000x.
Organelles are specialized structures that perform various functions in the cell.
1. Label: Locate each organelle in the animal cell. Label the organelles in the diagram below.
2. Match: Read about each organelle. Then match each organelle to its function/description.
H Cytoplasm
E Lysosome
F Mitochondria
A Centriole
G Endoplasmic reticulum
M Vacuole
D Plasma membrane
J Nucleus
L Ribosome
C Nuclear envelope
B Golgi apparatus
K Vesicle
I Nucleolus
A. Structure that organizes motion of chromosomes.
B. Stack of membranes that packages chemicals.
C. Membrane that protects the nucleus.
D. Membrane that surrounds and protects the cell.
E. Sac filled with digestive chemicals.
F. Structures that converts nutrients to energy.
G. Passageways where chemicals are made.
H. Jelly-like substance within the plasma membrane.
I. Structure that manufactures ribosomes.
J. Structure that contains DNA and directs the cell.
K. Package created by the Golgi apparatus. [Show Less]
