Click on any number to launch the unit of instruction. We suggest that you do "Levels of Organization" first. After that, sequence does not matter.


This  "Cells Are Us" module has five units of instruction The first unit is an introduction of the levels of organization in living systems, followed by four other units based on the main functions that cells must perform. Rather than discuss cells from the basis of their anatomy (membranes, mitochondria, nucleus, etc.), we thought it would be more interesting to emphasize what cells DO and why and how they do it.
