Cells

Eukaryotic Cells: nucleus and membrane-bound organelles

Prokaryotic Cells: DNA in cytoplasm; few, if any, organelles

Emergent Properties

Many processes only result as a result of complex interactions

Feedback

Negative Feedback: End product slows the process that creates that product

Positive Feedback (less common): High levels of end product increase production
