celldiagram.worldInteractive Cell Diagram Library
Cell diagrams you can click, hide, test and print
Every diagram here is a fixed vector drawing, labeled and checked against standard biology curricula. Click a structure to learn what it does, hide the labels to revise, play a round of Label-It to check you remember, then download a clean PNG for your homework or worksheet. No sign-up, no paywall.
Fixed vector diagram, drawn and checked against standard biology curricula — not AI-generated on the fly.
Try it right here — click any organelle.

Looking for a specific cell diagram? Start with one of these. Each page has the interactive diagram, a functions table, exam notes, FAQs and a self-test.
- Cell typeAnimal Cell DiagramNucleus, mitochondria, ribosomes, ER, Golgi apparatus and lysosomes, all labeled and clickable.
- Cell typePlant Cell DiagramCell wall, chloroplasts and the large central vacuole, with the parts animal cells share.
- ComparisonPlant vs Animal CellSide-by-side diagrams, a differences table and a Venn diagram of similarities.
Why these diagrams are different
- 01
Drawn once, checked properly
Each diagram is a fixed vector drawing reviewed against standard curricula — not generated fresh by AI each time, where organelle shapes and positions can drift.
- 02
A full learning loop
Read the labels, click an organelle for its function, hide the labels, then play Label-It and see whether you actually remember which structure is which.
- 03
Free downloads, no account
Export a labeled or blank PNG at double resolution, or print straight from the page. Fine for classroom handouts and homework.

Frequently Asked Questions
What is a cell diagram?
A labeled drawing of a cell that shows its structures — membrane, nucleus, mitochondria and so on — and lets you identify each one by name and function.
Which cell diagram do I need?
For most school biology it is either the animal cell or the plant cell. If your question is about differences, use the plant vs animal comparison page.
Are the diagrams free to use in class?
Yes. You can view, print and download labeled or blank versions free, with no account, for teaching and homework.
Is the site available in other languages?
English and Chinese are both live, and the labels inside every diagram switch language too because they are real text, not baked into an image.
