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 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 62. Movement of molecules

Select the cell animations that show the movement of molecules. Distinguish between:

1. Carrier mediated transport and active transport.

2. Endocytosis and exocytosis

Explain why such a variety of mechanisms for transport is required.
