Biology Research Overview

includes an interactive tour of the cell and discussions around questions: How do viruses attack cells? How will technology open new doors in biology? How can the mustard plant help us understand animals? How can neuroanatomy help us understand diverse life forms? How are fish and maple trees connected? What is life? (National Science Foundation)

Interesting Fact:

Although the cell is the smallest unit of life, it is by no means simple. The human body is made up of tens of trillions of cells. New research suggests such complex cells, which scientists call "eukaryotes," arose from the fusion of two simpler kinds of single-celled organisms in a symbiotic effort to survive.
