Biology resources.
Diagrams that teach.
Ready in two minutes.

Biology is a diagram subject. A plant cell with the wrong organelles labelled, a heart diagram with the vessels in the wrong place — these don't just lose marks, they teach misconceptions. AQA KS3 through A-Level, with correctly rendered diagrams built in from the start.

Spec alignment

Built on the spec.
Not on guesswork.

Biology at A-Level covers roughly twice the content of GCSE, and the language shifts significantly — 'respiration' at KS3 means something quite different from aerobic respiration and the Krebs cycle at A-Level. Every resource is built against a structured database covering the AQA KS3 National Curriculum (92 lessons), AQA GCSE Biology 8461 separate award, AQA Combined Science Trilogy 8464, and AQA A-Level Biology 7401/7402. Type the topic and level, and the generator matches the depth, command words, and required diagrams to exactly what you're teaching.

Why it matters: Generic AI tools write plausible-looking resources that miss spec points, use the wrong command words, or pitch the wrong tier. Biology resources from Print My Lesson are built on a structured database of spec points, so every question, slide, and mark scheme is anchored to what students will actually be assessed on.

Example spec coverage
  • KS3Cells — structure, specialisation, microscopy
  • KS3Body systems — digestion, circulation, reproduction
  • KS3Ecosystems — food webs, adaptation, variation
  • 4.1GCSE: Cell biology — structure, division, transport
  • 4.2GCSE: Organisation — organs, systems, enzymes
  • 4.4GCSE: Bioenergetics — photosynthesis, respiration
  • 4.6GCSE: Inheritance, variation and evolution
  • 4.7GCSE: Ecology — distribution, cycling, human impact
  • 3.1A-Level: Biological molecules — proteins, DNA, enzymes
  • 3.4A-Level: Genetics — inheritance, linkage, gene expression
  • 3.6A-Level: Organisms respond to changes — nervous, hormonal

Who it's for

For biology teachers who need diagrams they can trust.

Biology lessons rely on diagrams more than any other science. A heart diagram with the aorta mislabelled, a cell diagram missing the vacuole, a Punnett square set up wrong — these things teach misconceptions that students carry into exams. Print My Lesson renders biology diagrams from structured data, not from a language model's approximation of what a plant cell looks like.

What teachers ask first

The questions
you're already thinking.

Does it handle Combined Science vs Separate Biology correctly?
Yes. Combined Science Trilogy (8464) and Separate Biology (8461) are treated as distinct specifications. Resources for Combined are scoped to the Trilogy content — topics unique to Separate Biology, like the full content on kidney structure or the detailed nervous system, won't appear unless you ask for Separate.
What diagrams does it actually render?
Plant cell (correctly labelled with cell wall, chloroplast, large central vacuole, etc.), leaf cross-section, heart (chambers, valves, vessels correctly positioned), digestive system, lungs and gas exchange surface, and Punnett squares for genetics. These are rendered as diagrams on the page.
What about required practicals?
Required practicals are part of the spec coverage. Generate a lesson or question sheet on a specific RP — microscopy, osmosis, enzyme activity, field work techniques — and you get the method, analysis questions, and the skills AQA tests in the written exam.
Does it go deep enough for A-Level?
Yes. A-Level resources cover 7401/7402 content in full depth — gene expression, chi-squared analysis, photosynthesis and respiration biochemistry, homeostasis, ecology statistics. The depth is calibrated to A-Level, not a GCSE summary.
Can I set the lesson length?
Yes — choose from 45, 50, 55, 60, 70, or 75 minutes when generating a lesson slide deck. The resource is scoped and timed to match your period length.
Does it handle genetics properly?
Yes. Monohybrid and dihybrid crosses, codominance, sex-linkage, and gene linkage are all supported. Punnett squares are rendered correctly and mark schemes reflect how AQA expects genetic crosses to be set out.
Honest about where we fit

When to use us.
When not to.

We're not right for every job. Here's an honest picture of where other tools win and where we do.

Use them
Generic AI chatbots
Useful for explanations and drafting text. Less reliable for biology diagrams — organs and cells are typically described rather than rendered, and spec scope is approximate between Combined and Separate.
Use us
Print My Lesson
A lesson or question sheet with diagrams rendered on the page, spec scope matched to the level you asked for, and mark schemes that match how AQA awards marks.
Use them
Big resource libraries
Good for browsing. The trade-off is that existing resources weren't made for your specific class, tier, or required practical focus — adapting them to your needs takes time.
Use us
Print My Lesson
Generated for exactly the topic, level, and lesson length you specify. Faster than browsing and you can iterate on a genetics lesson or dissection practical in seconds.
