The image is bright green because of chlorophyll in the plant. It is interesting that you can see a grid of what I believe to be organized segments of the plant surface OR plant cells if you look at the darker lines in the picture. It is also interesting that you can detect a 3D texture from the image as some parts of the plant sample are elevated slightly.

The sample (right image below) was collected at 3:36 pm on 5/27/2019 at the California Institute of Technology, in a private garden at Ruddock House (1320 San Pasqual St, Pasadena, CA 91106). It was gently detached from a plant (see below).
