To identify the cell parts you can also try the cell inspector.
Or give a look inside the cell.
If you wanna have some fun learning about the origin of the eukaryotic cell, then follow this Cell Craft – a BIOLOGY GAME!
You can download the game here.
Or maybe you would prefer traveling into the cell, then here you have a whole Flash Movie Through the Virtual Cell, or you watch it step by step here. It has a got a higher level, mainly when explaining biochemistry, but is worth watching.
Finally in this web you have another interactive activity to identify the different parts of an animal cell (in that web there are some more learning objects related to these areas:Biology, Anatomy and Physiology, Microbiology, general Health).
Levels of organization.
A good explanation of the Levels of Organization within the human body,

Difussion and Osmosis.
But how do cells get the substances they need? To find it out give a look at this diffusion and osmosis video, to clarify that dissolved substances pass into and out of cells by diffusion. Water passes into and out of cells by osmosis.
With all this information you should make properly this test .
