7 cell PNG images with transparent background
Biology at cell level: a test tube of separated blood with yellow plasma above dark red cells, the skeletal formula of a drug-like molecule, and protein ribbon models — orange-brown helix bundles, a rainbow complex and a twisted chain shading from blue to orange.

From test tube to molecule
The pictures work at different scales. The blood tube shows what can be seen with the naked eye after a sample settles; the ribbon models zoom in to single proteins that do the work inside a cell; the structural formula goes further still, down to atoms and bonds. Choose the scale that matches the point of your lesson or article.
Diagrams that explain
A layered tube is the classic way to introduce plasma and red blood cells and the idea of the haematocrit. Ribbon models suit topics on enzymes, receptors and protein folding, while a skeletal formula belongs in chemistry or pharmacology material.
Keep labels readable
The formula and the tube already carry small lettering. When placing them on a slide, keep them large enough that the text stays legible, or crop to the part you discuss and add your own caption.
Questions and answers
Are all cell images really transparent?
All 7 images carry a real alpha channel. On the image page you can switch the backdrop to white or dark to see the edges.
Are there large files for print?
Originals range from 624 to 1 200 pixels. On download you can shrink to 64–1024 px; enlarging beyond the original is not offered.
How many files can I download?
No sign-up needed. The file is served after a short wait on the download page.
Can I use cell images commercially?
Personal and educational projects — freely. For commercial use check the rights with the original source, especially for logos, characters and photos of people.
