Topic 1.2: Ultrastructure of Cells
Essential Idea: Eukaryotes have a much more complex cell structure than prokaryotes.
At SHS, Topic 1.2 is taught in the following class unit(s):
Statements & Objectives:
1.2.U1 Prokaryotes have a simple cell structure without compartmentalization.
1.2.U2 Eukaryotes have a compartmentalized cell structure.
1.2.U3 Prokaryotes divide by binary fission.
1.2.U4 Electron microscopes have a much higher resolution than light microscopes.
1.2.A1 Structure and function of organelles within exocrine gland cells of the pancreas.
1.2.A2 Structure and function of organelles within palisade mesophyll cells of the leaf.
1.2.S1 Drawings of the ultrastructure of prokaryotic cells based on electron micrographs.
1.2.S2 Drawings of the ultrastructure of eukaryotic cells based on electron micrographs.
1.2.S3 Interpretations of electron micrographs to identify organelles and deduce the function of specialized cells.
1.2.NOS Developments in scientific research follows improvements in apparatus- the invention of the electron microscopes led to greater understanding of cell structure.
