John Kryk has got some fantastic explanation of cell biology on his website. Some of the explanation comes with animation too. If you are into cell biology, this site is worth checking out.
In addition, he has an interesting animation on evolution. Basically, you slide the arrow across time and life starts cropping up. It starts from the Big Bang and winds up with a web page teeming with life. Very educational, especially for kids!
