NOS:
Developments in scientific research follow improvements in apparatus—the invention of electron microscopes led to greater understanding of cell structure. (1.8)
Understandings:
Prokaryotes have a simple cell structure without compartmentalization.
Eukaryotes have a compartmentalized cell structure.
Electron microscopes have a much higher resolution than light microscopes.
Applications and skills:
Application: Structure and function of organelles within exocrine gland cells of the pancreas and within palisade mesophyll cells of the leaf.
Application: Prokaryotes divide by binary fission.
Skill: Drawing of the ultrastructure of prokaryotic cells based on electron micrographs.
Skill: Drawing of the ultrastructure of eukaryotic cells based on electron micrographs.
Skill: Interpretation of electron micrographs to identify organelles and deduce the function of specialized cells.
