caption: The image shows a cross section of a piece of paper with a black and white image of a cell, which appears to be a photo of cytomegalovirus. The cell is composed of a variety of cells, including a nucleus, mitochondria, and other organelles, all of which are visible in the photo. The cells are arranged in a pattern, with the nucleus in the center and the mitochondria radiating outward. The background of the image is a light blue color, and the cells are outlined in black.
