Green Onion Under the Microscope

A new set of stereo, reflected-light, microscopes came in last week, and I’ve been testing them out. MPU has a good eye for these things, so I asked him to collect some samples for examination.

The first thing he came up with was this beautiful green onion. The seed head has some remarkable colors, and the microscopes are of good enough quality that we could examine in quite good detail at 10x magnification. We were even able to see a few small insects hanging out on the seed head that would have been invisible to the naked eye. They didn’t like the light, however, and hid before I could get a good photo.
