Page 12. Cell structure and function
The diagrams represent two kinds of a cell. What are they? Test yourself on the identity of each of the structures in the two cells and then click on the structures to check your answers. Click again to play the animation.
Do the online quiz when you think you are ready.
Page 8. Cell size
Compare the size of a human hair, to that of a red blood cell and an ebola virus.
Page 15. Diversity of cells
View Mammalian cell types Parts 1 & 2. Choose 3 different mammalian cell types, and for each, by means of a simple diagram and annotations, relate the overall cell structure to its function.
What is a tissue? What structures do different cells have in common? Explain why there are differences between cells and tissues.
Page 18. Cells
Use your mouse to explore the organelles within cells. Look inside the organelles and learn more about what each organelle does.
Page 22. Microscopes and magnification
Choose onion root mitosis in the dropdown box. Click on the magnification from x25 - x1000. Draw the actual size of the sample of the onion root and two other diagrams of the cells of increasing magnification. Answer the questions that appear on the screen below the view.
Page 23. S.E.M
Try to get the best possible image by changing the contrast, brightness and magnification for each specimen viewed.
