Visitors to the National Science Foundation’s Biology Research Overview site are privy to an interactive tour that guides users through a three-dimensional image of a human cell, complete with numbered parts such as the mitochondria and the nucleus. Cutaways reveal the inner structure of the cell, along with detailed explanations as to how each component in the cell works with others. Students also can find information about the latest biology news and discoveries, while teachers can use the classroom resources provided on the site–such as web sites about biotechnology and botany–in their lesson plans. The site gives information on topics such as how climates affect life today, the role in technology in biology, and how living creatures evolved from single-celled organisms.
