It’s Tuesday, March 19, 2019, and time for for Science! I have a Recommended Website:to share with you this morning. Biology – A Tour of Cell.
Age Range: 11-18 (Grades 6-12, with parental supervision) Can you imagine how many millions of these tiny cells are inside of your body at this very moment? Amazing! This tour of a cell from the National Science Foundation is very detailed and informative.
“Although the cell is the smallest unit of life, it is by no means simple.”
Thus begins this brief-but-fascinating exploration. The opening picture is a large, full-color image of a cell. To begin, click on any of the numbered parts of the cell and a beautiful, detailed close-up image of that cell art will appear, along with one or two paragraphs of information about it. Parts featured include:
- the cell membrane
- DNA
- RNA
- endoplasmic reticulum
- mitochondria
and more.
Once you have viewed a part of the cell, you will see small numbers below the photo of that part. These numbers provide a convenient way to navigate through the site sequentially, if you prefer. If you click “Explore More,” you will go back to the main page.
