Essential Idea
Eukaryotes have a much more complex cell structure and than prokaryotes.
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
Structure and function of organelles within exocrine gland cells of the pancreas (VIDEO).
Structure and function of organelles within palisade mesophyll cells of the leaf.
Prokaryotes divide by binary fission (VIDEO).
Skills
Drawing of the ultrastructure of prokaryotic cells based on electron micrographs.
Drawing of the ultrastructure of eukaryotic cells based on electron micrographs.
Interpretation of electron micrographs to identify organelles and deduce the function of specialized cells (VIDEO).
Guidance
Drawings of prokaryotic cells should show the cell wall, pili and flagella, and plasma membrane enclosing cytoplasm that contains 70S ribosomes and a nucleoid with naked DNA (VIDEO).
Drawings of eukaryotic cells should show a plasma membrane enclosing cytoplasm that contains 80S ribosomes and a nucleus, mitochondria and other membrane-bound organelles are present in the cytoplasm. Some eukaryotic cells have a cell wall (VIDEO).

Learning Activities
Comparing Prokaryotes and Eukaryotes
This simple table clarifies the major similarities and differences between prokaryotic cells and eukaryotic cells.
This game, prepared by McGraw-Hill, is similar to Trivial Pursuit but related to cellular organelles and processes.
Three simple tutorials, games and quizzes, prepared by Sheppard Software, to help you learn/remember the various structures of animal, plant and bacterial cells as well as their respective functions.
Cell Labeling Games
Use the following links to race against the clock in games that improve your identification skills.
Match organelles with their respective functions and label a diagram.
Similar to the previous worksheet. Extra practice is never a bad thing.
Take this quiz to check your understanding of the various organelles within a eukaryotic cell.
