| Lesson Topic: describe and interpret photomicrographs, electron micrographs and drawings of typical plant and animal cells |
Learning Objective/s:
- Describe the key structural differences between typical plant and animal cells.
- Interpret photomicrographs and electron micrographs to identify cell type and major organelles.
- Compare light microscopy, TEM and SEM and select the appropriate technique for a given cellular feature.
- Apply this knowledge to answer exam‑style questions on cell diagrams and micrographs.
|
Materials Needed:
- Projector or interactive whiteboard
- PowerPoint slides with photomicrographs, TEM and SEM images
- Printed worksheets with labelled plant and animal cell diagrams
- Microscopy handout summarising techniques and key features
- Whiteboard and markers
- Exit‑ticket cards for the final check
|
Introduction:
Start with a quick poll: which cell structures can you already recognise in a microscope image? Students recall previous work on cell organelles and basic microscopy. Today they will learn to distinguish plant and animal cells using photomicrographs, TEM and SEM images. Success is shown by accurately labeling a mixed set of cell images.
|
Lesson Structure:
- Do‑now (5'): Students label a simple plant cell diagram from memory.
- Mini‑lecture (10'): Review light microscopy, TEM and SEM and highlight key plant vs. animal cell features using slides.
- Guided analysis (15'): Small groups examine a set of photomicrographs; identify cell type and organelles, record observations.
- Electron‑micrograph challenge (10'): Groups compare TEM/SEM images, discuss ultrastructural clues.
- Whole‑class debrief (10'): Share findings, clarify misconceptions, emphasise SA:V and vacuole relevance.
- Practice exam question (10'): Individually answer a past‑paper item requiring interpretation of a cell drawing.
- Exit ticket (5'): Write one key difference they can now spot in any micrograph.
|
Conclusion:
We revisited how different microscopy techniques reveal distinct cellular details and practiced interpreting real images. To consolidate, complete the online quiz on cell identification before the next lesson. Review the summary handout for quick reference and be ready for the upcoming assessment.
