National Science Foundation: Tour of the Cell

A cell happens to be the smallest unit of life, but there's a tremendous amount of activity going on within this very fascinating place. The talented people at the National Science Foundation (NSF) are well aware of this fact, and they have created this illuminating and interactive visual feature to
help people learn about the cell's different components. On the homepage, visitors are presented with a clickable illustration of the cell's primary components, including the nucleus, the cell membrane, and mitochondria. Clicking on any of these various items brings up a detailed illustration, complete with a brief description of its function. Finally, visitors can also view the complete illustration by clicking on the "Full Illustration" link.
