STEVE GSCHMEISSNER/SCIENCE PHOTO LIBRARY Blood clot. Coloured scanning electron micrograph (SEM) of red blood cells (erythrocytes, red) clumped together with fibrin (brown) to form a blood clot. Magnification: x5000.
I love the detail in this! This is a plant cell. The range of sizes of circles makes it very eye catching and interesting to look at. It makes you want to look closer which makes a great image. Again this could be easily repeated and continued to create a print.
