The Life of a Cell
A View of the Cell
Follow the link to this site for descriptions of how cells respond to various invaders, including HIV, bacteria, and a splinter. Which of the white blood cells are the most active?
This site provides a good history of cell biology and links to colorful graphics of cell organelles as well as comprehensive explanations of their functions. How many cells does the
human body have? Click on the animal cell link to learn what feature is missing from animal cells but is found in plant and fungi cells.
Scanning Probe Microscopy
This site is maintained by an organization that collects experimental evidence in biology, chemistry, and phyics using a scanning probe microscope. Explain to a friend how the scanning
probe miscroscope images of DNA differ from images of chromosomes.
This site explains how electron microscopes work, including some pictures and the difference between SEMs and TEMs. Develop a presentation that explains how electron microscopes are
different from light microscopes.
This is an excellent site that has a variety of virtual microscopes that students can explore. Each type of microscope has instructions for focusing, light adjustments, and magnification.
Choose one of the microscope types and explore the various features of each. Select an organism and make a detailed drawing of it.
This is a brief biographical entry about Lewis Thomas. What award did he win for his collection of essays that appeared in the New England Journal of Medicine?
Unit 3: The Life of a Cell
Hydrogen Bonding in Organic and Biochemistry
Access this site to learn how hydrogen bonding occurs and its importance in biology. What kind of forces are at work in a hydrogen bond? Create a poster by drawing diagrams of the different
Follow the link to this site to take a 3-D navigational tour through a plant cell. What structure is unique to plant cells? View an electron micrograph of a real plant cell and compare
it to the virtual cell in a journal article.
The Cell Nucleus I
Visit this site to focus on the cell nucleus. Use this information to make a 3-D model of a human cell.
This site covers cells in detail. Visit it to learn about the different types of cells and their purpose. Visit the Cell Gallery and write a journal entry describing the properties of
three different types of cells.
