About This MicroSim

This interactive diagram displays a prokaryotic bacterial cell and a eukaryotic animal cell side by side, with 15 labeled structures. Students can explore each structure by hovering over numbered markers or labels to read descriptions and AP Biology exam tips. Quiz mode tests structure identification with immediate feedback and a celebration animation on completion.

How to Use

  1. Explore mode: Hover over any numbered marker on the diagram or click a label in the side panel to read about that structure.
  2. Quiz mode: Click the Quiz button. The infobox will prompt you to click on a named structure. Correct answers reveal the label; incorrect clicks give feedback.
  3. Edit mode: Append ?edit=true to the URL to drag markers and calibrate their positions.

Lesson Plan

Grade Level

9-12 (AP Biology)

Duration

15-20 minutes

Prerequisites

Basic understanding of cell theory and the difference between living and non-living things.

Activities

  1. Exploration (7 min): Students hover over each structure on both cells, recording which structures are unique to prokaryotes, unique to eukaryotes, and shared by both.
  2. Guided Practice (5 min): Ask: "What is the single most important structural difference between prokaryotes and eukaryotes? Why does compartmentalization matter for eukaryotic cell function?"
  3. Assessment (5 min): Students complete Quiz mode, identifying all 15 structures. Discuss: "How does endosymbiotic theory explain the presence of 70S ribosomes in mitochondria?"

Assessment

  • Students can name and locate structures unique to prokaryotes (cell wall, nucleoid, plasmid, flagellum, pili).
  • Students can name and locate structures unique to eukaryotes (nucleus, nucleolus, rough ER, Golgi, mitochondria, lysosomes).
  • Students can identify shared structures (plasma membrane, ribosomes, cytoplasm, DNA) and explain key differences (70S vs. 80S ribosomes, circular vs. linear DNA).
  • Students can explain endosymbiotic theory using evidence from mitochondrial structure.
