Cards (22)

  • How do prokaryotic cells differ from eukaryotic cells?(size)
    Prokaryotic cells are much smaller
  • What is the standard unit of measurement in science?
    The meter
  • Why are objects in biology often measured in smaller units?
    Because they are often much smaller than a meter
  • What does the prefix "centi" mean?
    One hundredth
  • How many centimeters are in a meter?
    100 centimeters
  • What is the standard form of 1 centimeter?
    1 * 10^-2 meters
  • What does the prefix "milli" mean?
    One thousandth
  • How many millimeters are in a centimeter?
    10 millimeters
  • What is the standard form of 1 millimeter?
    1 * 10^-3 meters
  • What does the prefix "micro" mean?
    One millionth
  • How many micrometers are in a meter?
    1,000,000 micrometers
  • What is the standard form of 1 micrometer?
    1 * 10^-6 meters
  • What is the typical size range of a human cell?
    Around 10 to 20 micrometers
  • Why is the micrometer a useful unit for biologists?
    It is suitable for measuring cell sizes
  • What is the smallest unit discussed for measuring objects inside cells?
    The nanometer
  • What does the prefix "nano" mean?
    One billionth
  • How many nanometers are in a meter?
    1,000,000,000 nanometers
  • What is the standard form of 1 nanometer?
    1 * 10^-9 meters
  • Why are proteins and cells measured in nanometers?
    Because they are very small sizes
  • What are the key differences between eukaryotic and prokaryotic cells?
    • Eukaryotic cells are larger
    • Eukaryotic cells have a nucleus
    • Prokaryotic cells are smaller
    • Prokaryotic cells lack a nucleus
  • What are the standard forms for the prefixes discussed?(Centimeter, millimeter, micrometer, nanometer)
    • Centimeter: 11 *102 m 10^{-2} \text{ m}
    • Millimeter: 11 *103 m 10^{-3} \text{ m}
    • Micrometer: 11 *106 m 10^{-6} \text{ m}
    • Nanometer: 11 *109 m 10^{-9} \text{ m}
  • What are the implications of using different size units in biology?
    • Allows precise measurement of small structures
    • Facilitates understanding of cellular components
