Student Exploration: Cell Structure
Vocabulary: cell membrane, cell wall, centriole, chloroplast, cytoplasm, endoplasmic reticulum, Golgi apparatus, lysosome, mitochondria, nuclear membrane, nucleolus, nucleus, organelle, plastid, ribosome, vacuole, vesicle
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
- What are some of the structures inside a cell that help it to live and perform its role in an
organism? _nucleus-control center, vacuole-storage, ribosomes-synthesize proteins, lysosome-digest bad things.
- How do you think plant cells differ from animal cells? (Hint: What can plants do that animals
cannot?) Plant cells have chloroplast that allow them to get their energy from photosynthesis. Animal cells cannot do so as they receive their energy from cellular respiration, in the mitochondria.
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 (200 0 times larger than normal). On the dropdown menu, select Centrioles.
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.
Read the description of the centrioles. What is their function Organize the movement of chromosomes dring cell division.

Activity A: Animal cells
Get the Gizmo ready: Check that an Animal cell is mounted on the microscope. Check that the Zoom is set to 2000x.
Question: Organelles are specialized structures that perform various functions in the cell. What are the functions of the organelles in an animal cell?
Label : Locate each organelle in the animal cell. Label the organelles in the diagram below.
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 Cell membrane J Nucleus L_ Ribosome C Nuclear membrane 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 cell membrane. I. Structure that manufactures ribosomes. J. Structure that contains DNA and regulates genes. K. Package created by the Golgi apparatus. L. Small structure that synthesizes proteins. M. Sac that stores water, nutrients, or waste products.
