“Virtual Cell” Activity
Go to www.virtualcell.com, then CLICK on “The Virtual Textbook”, then CLICK on “Cell Biology” to begin.
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.
