Many of the organelles can have their outer membranes cut off or be dismantled to show their interior structures. Visitors control the image rotating left or right and zooming in and out with navigation buttons. The text explains the function of the organelles and any special information related to them. For example, the mitochondrion can be seen with its outer membrane cut off first and then with the inner membrane removed. The Virtual Textbook, which is a work in progress, contains color animated drawings to illustrate the concepts within the online chapters.
Hyperlinks connect visitors to specific subjects within each chapter.
Chapters are planned in biology, chemistry, physics, and math.
