Science Art: Helical Granum, by Kelvinsong

Click to embiggen

Though it looks like postmodern architecture (Eero Saarinen, maybe?), this is actually inside your salad.

It’s a helical granum of a thylakoid stack, the part inside a plant cell – inside a chloroplast – where photosynthesis takes place. A thylakoid membrane forms a package inside which one thylakoid disk is stacked on top of another. The stack is called a granum. Some of them, like this one, make a kind of spring-like spiral… so not only do leaves fall in fall, but at a sub-cellular level, some will spring in spring, too.

I found this on Wikimedia Commons, where Kelvinsong does some really nice work.
