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 circular pattern, with the nucleus in the center and the mitochondria radiating outward. The colors of the cells range from light blue to dark blue, and the background of the image is a light gray.
