Student Exploration: Cell Structure
Vocabulary: cell wall, centriole, chloroplast, cytoplasm, endoplasmic reticulum, Golgi apparatus, lysosome, mitochondria, nuclear envelope, nucleolus, nucleus, organelle, plasma membrane, plastid, ribosome, vacuole, vesicle Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. What are some of the structures inside a cell that help it to live and perform its role in an organism? ____________________________________________________________
_____________ 2. How do you think plant cells differ from animal cells? (Hint: What can plants do that animals cannot?) ____________________________________________________________
_____________ 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. Make a sketch of the centrioles in the space below.
2. Read the description of the centrioles. What is their function? ________________________ ____________________________________________________________
Get the Gizmo ready: Activity A: Animal cells • Check that an Animal cell is mounted on the microscope. • Set the Zoom to 500x.
Question: Organelles are specialized structures that perform various functions in the cell. What are the functions of the organelles in an animal cell? 1. Label: Locate each organelle in the animal cell. Label the organelles in the diagram below.
2. Match: Read...
