Cells- the Legos of Organisms
Cellular investigation:
For further exploration of cell parts and functions be sure to check out this virtual microscope , go to Cells Alive and go on a cellular vacation tour, and go to Harvard for a few minutes and get a microscopic diploma. Watch the clips below to learn more about cell theory and organelles.

Here is a good interactive site for naming the organelles of cells.
Metaphors for organelle functions.
Here are some raps to help you remember.

Or go to youtube if you can get around the filter for an in depth tutorial.
Cell Membrane
The fluid mosaic model is so named because of the proteins and carbohydrates studded throughout the membrane. Look at some artistic mosaics and then at some pollen cells to see the similarities.
Try out this interactive model to see the different ways molecules use to pass through a membrane.

Bacteria: Prokaryotic cells with cell membranes and DNA and occasionally cell walls exist in a variety of shapes like spheres, rods, and spirals. Bacteria make up most of the bio-mass of our planet, can live almost anywhere, and even outnumber our own 'human' cells in our bodies, yet some can be quite harmful.
Stromatolite bacteria helped oxygenate our atmosphere.
Bacteria are used in food production and by the medical community.
Bacteria can reproduce asexually (video) or sexually.

Active Transport
Diffusion is just so passive. Lets talk about active transport. Endocytosis, exocytosis, and phagoscytosis all move molecules against the concentration gradient; like walking uphill that takes energy. It creates even less of a balance.
