Your Lichen Project Continues:
Here are you criteria for this week. I’ll be uploading the slides as I go. Enjoy!
Use a light microscope State why microscopes are useful in the study of cell biology Calculate total magnification |
Describe the difference between magnification and resolution.
Describe the advantages and disadvantages of using a light and electron microscope. Use the formula: image size = specimen size × magnification. |
Compare and contrast the magnification and resolution obtained by using light and electron microscopes. Justify the use of an electron microscope. Rearrange the magnification equation and measure the size of cells. |
Identify structures in prokaryotic cells. State that bacterial (prokaryotic) cells do not contain a nucleus and eukaryotic cells do. Use orders of magnitude to correctly order objects according to size. |
Compare prokaryotic and eukaryotic cells.
Describe the functions of the parts of a prokaryotic cell. Use orders of magnitude to compare sizes of organisms. |
Explain how the main structures of prokaryotic cells are related to their functions. Perform calculations to work out orders of magnitude. |
Identify specialised plant cells from diagrams. Recall the function of specialised plant cells. Use a light microscope to view a root hair cell. |
Compare the structure of a specialised and generalised plant cell.
Describe the adaptations of specialised plant cells. Draw a scientific drawing of a root hair cell observed using a light microscope. |
Discuss how the structure of specialised plant cells are related to their function within the organ and whole organism. Design a cell, tissue, or organ to perform a certain function. Measure a root hair cell observed using a light microscope. |

I’ve given you some feedback! Please respond when you get chance!
The Microscope’s has opened up so many doors to science. Thanks to microscopes, we’ve discovered microorganisms, study the structure of cells and see the smallest parts of plants, animals, and fungi. The microscope is still used to diagnosis illnesses in hospitals and clinics everywhere. Microscopes have been moved beyond the visible light refracting lenses.Electrons, x-rays and infrared rays are used by far more expensive microscopes to detect even the smallest structures. Scanning electrons microscopes are able to resolve viruses, which are far smaller then any cell.
So what are the advantages and disadvantages of using each of these two types of microscopy?
