In addition to the lasers and lights, the team placed the plants on a rotating plate to figure out how they're affected by gravity in the cellular scale. Its results will help scientists figure out the best way to grow plants in space. The team's method, however, works with organisms other than plants: they even used it to watch cells move around in zebrafish embryos. While they unfortunately didn't share footage of that experiment, you can watch root cells grow in the video below.
