Microscoopopname van de kern van een tarweplant before 1892

This photomicrograph by Robert W. Dunham, taken before 1892, shows a portion of the inner skin on a cutting of Cerealia cells. The image is a close-up of the grain magnified at 400 diameters. The image is a visual representation of the scientific and artistic process of capturing and observing the microscopic world, a technique that became increasingly important in the late 19th century.
