Marijuana Female Flower, SEM Bract and Stigma

A scanning electron microscope image of the football shaped bract of the female cannabis (Cannabis sativa) flower. The oval bract structure houses the stigma and is responsible for producing seeds when the flower has been pollinated. This bract structure is also the location of the highest concentration of cannabinoid compounds on the plant. This site is also the location of the highest concentration of THC. There are a number of different types of cell structures called trichomes in this image. The thorn-like trichomes use a physical defense while the circular glandular trichomes use chemical defense. Combined, these defenses keep insects and animals from eating the plant. Each circular glandular trichome is 50 um in diameter in this image. The filed of view of this image is 3 mm wide.

The Kinsman Project

Art meets science in this uniquely stunning photograph created by Professor Ted Kinsman of the Photographic Sciences Department at the Rochester Institute of Technology, where he teaches High-Speed Photography and Scanning Electron Microscopy (SEM). His expertise in cutting-edge scanning electron microscopy,light micro graphs, x-rays, and computational photography, combine to reveal the extraordinary microscopic beauty of the world’s most controversial plant: cannabis Sativa.

Professor Kinsman has compiled 140 images, over the course of three years, into a book, Cannabis: Marijuana Under the Microscope, which describes the great precision, planning, knowledge, and skill required to produce these incredible Images.

We, at Nu-Venture, LLC, are proud to have taken professor Kinsman’s SEM photographs to a new, distinctive level by producing them in 3D Lenticular imagery. We sincerely hope that this series of stunning Scientific Cannabis Photo Art pleases you enough to share the beauty.
