Virtual Cell Activity
Directions:
Go to http://www.ibiblio.org/virtualcell/index.htm.
Click on “The Virtual Textbook”, then click on Ch. 3 Cell Biology to begin.
Background Information
The “virtual cell” will allow you to get a close-up view of several organelles in 3-D! You will be able to
choose certain organelles within the cell and manipulate them by zooming in on the organelle, rotating
the image, and dissecting several organelles to view their contents. The intent of the activity is to
provide you with a better feeling of the appearance (structure), function and location of the organelle.
While navigating this site you will click on “Next page” at the bottom of the screen to move to the next
page and answer each of the following questions.
After viewing and studying an animation, some items ask you to place a check in the corresponding
box to indicate that you viewed the animation.
