Microscopy image baseline
Mon, Nov 16, 2026 · Week 13 · Genetics of Disease (Medical Interventions)
Today's goal: Use cell and tissue images to establish a baseline for normal versus abnormal morphology and a diagnostic workflow.
This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.
Morphology comparison (benign vs. malignant):
- Cell size and shape: benign cells are uniform and look alike; malignant cells are pleomorphic, meaning they vary in size and shape.
- Tissue arrangement: benign tissue keeps an orderly, organized structure; malignant tissue is disorganized and loses normal architecture.
- Boundaries: a benign tumor stays in one place with a clear edge; a malignant tumor pushes into and invades the surrounding tissue.
Metastasis (one line): The metastasis image differs from a local tumor because cancer cells have left the original site and traveled through blood or lymph to a distant organ, instead of staying put.
Diagnostic workflow (three steps):
1. Take a tissue sample (biopsy) and prepare it on a slide.
2. Examine the cells under the microscope for size, shape, and arrangement.
3. Classify the tumor as normal, benign, or malignant, and note any sign of invasion or spread.
| Feature | Benign tissue | Malignant tissue |
|---|---|---|
| Cell size and shape | Uniform, alike | Pleomorphic, varied |
| Arrangement | Orderly architecture | Disorganized |
| Boundary | Stays local, clear edge | Invades surrounding tissue |
This model shows the level of evidence and organization needed to complete: Completes the cancer-launch baseline task: a two-column comparison of benign versus malignant tissue morphology, a one-line metastasis explanation, and a three-step diagnostic workflow sketch.
- State the question and method.
- Present the observations and data with units.
- Explain the result, limitations, and next investigation.
Keep the structure. Replace the question, facts, measurements, and evidence. Then recheck units, vocabulary, and whether the conclusion goes beyond the evidence.
Also due today: Submit your morphology comparison and workflow sketch to Schoology before end of block.

Claim ceiling: Today's evidence supports a classroom claim about microscopy image baseline. It cannot prove causation, diagnose a real patient, or justify action outside this room.
One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.

It builds this reusable test skill: Reading cell and tissue morphology to tell normal from malignant.
- Name the concept or data pattern being tested.
- Cross out choices that violate that rule or the evidence.
- Justify the best remaining choice before checking the answer.
