1. 1.2 Ultrastructure of cells
Understanding:
Prokaryotes have simple cell structure without compartments
Eukaryotes have a compartmentalized cell structure
Prokaryotes divide by binary fission
Electron microscopes have a much higher resolution that light microscopes
Skills:
Drawing the ultrastructure of prokaryotic cells based on electron micrographs
Drawing the ultrastructure of eukaryotic cells based on electron micrographs
Interpretation of electron micrographs to identify organelles and deduce the function of specialized cells
Applications:
The structure and function of organelles within exocrine gland cells of the pancreas
The structure and function of organelles within palisade mesophyll cells of the leaf
Nature of science:
Developments in scientific research follow improvements in apparatus: the invention of electron microscopes led to greater understanding of cell structure

2. Microscopes
Create a table to describe the key differences between the three types of microscopes:
Light microscope
Transmission electron microscope
Scanning electron microscope
Studied microorganisms
Microscope ‘invented in 1590s’ still disputed
Monks cells = cells
Understanding:
Electron microscopes have a much higher resolution that light microscopes
Nature of science:
Developments in scientific research follow improvements in apparatus: the invention of electron microscopes led to greater understanding of cell structure

3. Light Microscope
Thin specimens Requires staining Limited magnification Most commonly used Living or dead specimens

5. Transmission Electron Microscope
Thin specimens Beam of electrons Far greater range of magnification with much improved resolution Expensive, used mostly in research Dead specimens

7. Scanning Electron Microscope
Beam of electrons 3D image Crystal clear resolution at high magnifications Specimens coated in heavy gold ions Expensive, used mainly in research and specialist labs Dead specimens

9. Vs.
Eukaryote
Prokaryote

10. Eukaryotes vs. Prokaryotes
Create a poster in pairs
Prokaryote and eukaryote.
For each cell:
Drawing and labels
What each organelle does
Examples of that type of cell
How they divide
Summarize the similarities and differences between them
Make them as beautiful as possible so I can put them on the wall!
THEN: Draw and explain the structure and function of organelles within exocrine gland cells of the pancreas and within the palisade mesophyll cells of the leaf
