Introduction
• Modern cell theory
• Different types of cells– prokaryotic, eukaryotic
• Three cell components– cell membrane, genetic material, cytoplasm
• Five kingdoms
• Three domains

Putting Away the Microscope
• Remove the slide and return it to its proper place
• Turn down the rheostat to “3” or lower
• Turn off the illuminator switch.
• Revolve the nosepiece so the 4X objective is in place.
• Cover the microscope with its cover.
