microscope

• What is the primary function of microscopes?

  To magnify images of specimens
• What did early microscopes look like?

  They looked much simpler than modern microscopes
• What important discoveries have light microscopes allowed us to make?

  Discoveries about the structures inside cells, such as the nucleus
• What are the limitations of light microscopes regarding magnification?

  They have a limited magnification that cannot easily view structures inside the nucleus
• What does limited resolution in light microscopes mean?

  It means the image is blurred, preventing fine detail from being seen
• Why was the electron microscope invented?

  To explore structures inside cells in detail
• What are the key advantages of electron microscopes over light microscopes?

  They have much greater magnification and resolution
• What can be seen in the nucleus when using an electron microscope?

  Detail in the nucleus that cannot be seen with a light microscope
• What is the formula for calculating magnification?

  Magnification = size of the image / size of the real object
• If the size of the image is 45 mm and the real nucleus diameter is 0.01 mm, what is the magnification?

  The magnification is 4,500 times
• If the length of the real mitochondrion is 0.3 mm and the image size is 30 mm, what is the magnification?

  The magnification is 100 times
• How do you calculate the size of the real object using magnification?

  Size of the real object = size of the image / magnification
• If the size of the image is 87 mm and the magnification is 2,000 times, what is the size of the real cell?

  The size of the real cell is 0.0435 mm
• What are the advantages of using an electron microscope compared to a light microscope?

  • Greater magnification
  • Higher resolution
  • Ability to see fine details in specimens
• What steps should you follow to calculate magnification?

  1. Measure the size of the image.
  2. Measure the size of the real object.
  3. Use the formula: Magnification = size of the image / size of the real object.
• How can you find the real size of an object if you know the image size and magnification?

  • Use the formula: Size of the real object = size of the image / magnification.
• What is the typical magnification limit of light microscopes?

  • Light microscopes have a limited magnification that cannot easily view structures inside the nucleus.
• What is the significance of resolution in microscopy?

  • Resolution determines the clarity of the image and the ability to see fine details.
