Part 2 • Venn Sorting Canvas
8 lines provided per category for structures & notes
Prokaryotes Zone A
Nucleoid (No Nucleus)
Prokaryotes only (note if none from list):
Write Structures / Notes:
Shared By Both Zone B (Both)
Membrane • Ribosomes • DNA
Shared structures found in both:
Write Shared Structures:
Eukaryotes Zone C
True Nucleus & Organelles
Found only in eukaryotes:
Write Eukaryotic Structures:
Part 3 • Venn Diagnostic Problem
Error Analysis
Scenario: A student places ribosomes and DNA into Zone A (Prokaryotes only), claiming that "bacteria are simple, so they need their own simple DNA and ribosomes."
Problem 1: Correct the Error Why is placing ribosomes and DNA only in Zone A incorrect? Where do they truly belong?
Problem 2: Organelle Analysis What fundamental membrane feature unites the nucleus, mitochondria, and endoplasmic reticulum in Zone C?
