• Biologists use microscopes and tools of biochemistry to study cells.
• Eukaryotic cells have internal membranes that compartmentalize their functions.
• The eukaryotic cell's genetic instructions are housed in the nucleus and carried out by the ribosomes.
• The endomembrane system regulates protein traffic and performs metabolic functions in the cell.
• Mitochondria and chloroplasts change energy from one form to another.
• The cytoskeleton is a network of fibers that organizes structures and activities in the cell.
• Extracellular components and connections between cells help coordinate cellular activities.
