- We Put "Special" in Plant Cell Specialization
      Think plants are uninteresting? Think again. The University of Hawaii brings you color-enhanced stained cell photos illustrating the different types of cells found in plants. These cells perform many functions; some transport food or water, while others provide protection or support. Be sure to check out the epidermis section. 
- You've Got Some Nerve!
      Nerve cells are long and skinny, which helps them send messages quickly from the brain to other parts of the body. This University of Washington website provides fascinating facts about neurons and how they differ from other cells. Scientists once believed the brain couldn't grow new neurons in adulthood find out if they may have been wrong.

- Hearing and Ear Cilia
      Cilia are found on some cells to propel them around. However, cilia are also vital to our sense of hearing. Their ability to vibrate allows them to pick up sound waves in our ear. Howard Hughes Medical Institute has a megasite devoted to the senses of smell, hearing, and sight, and this webpage is devoted to the mechanism of hearing with cilia.
- Blood Cells
      Blood is red, but it is composed of several components, including white and red cells, platelets, and plasma. Each of the cells found in blood has a specific function. The Fun Science Gallery posts photos and drawings exploring the specifics of blood. You can even learn how to view blood under a microscope (but don't try this unless you have your teacher's permission and supervision!).
White Blood Cells White blood cells, or leukocytes, provide immunity to disease. See the different types of leukocytes that work to keep your body healthy.
