Microscopy

• Why are microscopes important for biology?

  They allow us to see small objects.
• What do microscopy techniques allow us to do?

  They enable observation of microscopic details.
• What do light microscopes use to form an image?

  Light and lenses
• What do electron microscopes use to form an image?

  Electrons
• How do electron microscopes compare to light microscopes?

  They have a much higher resolution.
• What does resolution refer to in microscopy?

  Ability to distinguish between two points.
• What advantage do electron microscopes provide in terms of detail?

  They allow viewing of smaller structures.
• What tiny structures can electron microscopes reveal?

  Ribosomes and plasmids
• What is the formula for calculating magnification?

  magnification = image size / real size
• Why is standard form useful in microscopy?

  It simplifies very large or small numbers.
• What are the key features of light and electron microscopes?

  • Light microscopes:
  • Use light and lenses
  • Lower resolution
  • Electron microscopes:
  • Use electrons
  • Higher resolution
  • Can view smaller structures
• What is the significance of using standard form in microscopy?

  • Simplifies large/small numbers
  • Makes calculations easier
  • Facilitates understanding of measurements
