Cells Alive – Internet Lesson
URL: www.cellsalive.com
Objective: You will look at computer models of cells; learn the functions and the descriptions of the
cells and their components.
Navigating the Site: In the Table of Contents, click on Cell Models. Click Plant and animal cells. Answer
these questions:
1. Describe a eukaryotic cell. (Comment on their size, specialized structures, and give examples.)
Part A -- Click on “Start the Animation”, then choose “Animal Cell”. You will need to click on various
parts of the cell to go to a screen that tells you about the parts. Answers to the following questions are
found there.
Make a sketch of the organelle in the box.
1. What do mitochondria do?
Mitochondrion
2. How big are mitochondria?
3. What does the Golgi Apparatus do?
Lysosome
4. What is the difference between smooth & rough ER?
Golgi Apparatus
5. Where is the nucleolus found?
6. What does the nucleolus do?
Rough ER
7. What does the cytoskeleton do?
CellsAlive, p. 2
8. Cytosol goes by what other name?
9. What is the function of the cytosol?
10. What is the function of the lysosome?
Part B – Plant Cell Click on “Plant Cell.”
Sketch the following:
1. What other type of cell has a cell wall?
Chloroplast
2. What makes the plant cells green?
Vacuole
3. In plant cells, what does the vacuole do?
Part C – Bacterial Cell Scroll to the top of the page where it says “View Bacteria Cell Model.” Click
this.
Cellsalive, p. 3
Part D – How Big Is A . . . Go back to “cellsalive.com”. Click on “How Big is a…?” in the Table of Contents.
Follow the directions to view the animation.
1. E. coli and Staphylococcus are both bacteria. At what magnification can you see them well? ______________
2. Name something in the animation that is smaller than a bacterium. _________________________________
Part E – Overview
For the chart below, place a check in the box if the cell has that component.
Plant
Animal
Bacterium
Chloroplast
Vacuole
Ribosome
Mitochondria
DNA
Endoplasmic Reticulum
Cell Wall
Golgi Apparatus
When you are finished with this lesson, take out your science notebook. Write today’s
date and copy the learning objective (written below). Write at least a FIVE SENTENCE
reflection under the learning objective about today’s activity, the differences between
the organelles, and the differences between prokaryotic and eukaryotic cells. We will
be sharing these paragraphs in class.
If you finish the activity and science notebook early, you may work in your group on
planning your cell organelle projects, or explore more of the functions on the Cells Alive
Website. Be sure to turn this paper in before you leave!
Learning objective: Identify the function and structure of cell organelles in
eukaryotic and prokaryotic cells.
