cell structure

• what are eukaryotic cells?

  they have their genetic material (DNA) enclosed in the nucleus
• what do eukaryotic (plant and animal) cells contain?

  • cell membrane
  • cytoplasm
  • genetic material enclosed in the nucleus
• what are prokaryotic cells?

  their genetic material (DNA) is not enclosed in the nucleus
• what do prokaryotic (bacterial) cells contain?

  • cell membrane
  • cytoplasm
  • cell wall
  • single loop of DNA
  • plasmids (one or more small rings of DNA)
• prokaryotic cells (bacterial) are much smaller than eukaryotic
• what is order of magnitude?

  when every order of magnitude is 10X greater than the one before

  e.g 100X = 2 zeros so two orders of magnitude
