| Animal Cells |
Pictured here is a typical animal cell.
All animal cells are composed of
definite structures called organelles.
Animal and plant cells share many
key organelles, but the major
differences are that animal cells lack
cell walls, chloroplasts, and a central
vacuole. Animal cells occur in a
wide range of shapes, but most are
spherical like the one here.

information about each organelle.

| Before continuing on to "Check Your Knowledge" you may want to view this QuickTime movie of a Journey Into the Cell. The movie describes many of the cell's organelles covered here as well as several others. (The file is 8.43 MB so it may take a long time to download depending on your Internet connection speed. You can download the QuickTime player here if necessary.) Movie from: http://www.nslc.wustl.edu/courses/Bio381/movies.html |

| For revision, you will now go to the "Check Your Knowledge" site to complete the labelling exercise on the ANIMAL cell. Once you have correctly labelled all nine organelles, print the results page to hand in to your teacher. |
