Resolution is limited by the shortest wavelength of the radiation used for imaging.It is the minimum distance two points can be separated and still be distinguished as two separate points.Resolving power is a measure of image clarity.Magnification is the ratio of an object’s image to its real size.Microscopes vary in magnification and resolving power.The lenses refract light such that the image is magnified into the eye or onto a video screen.In a light microscope (LM), visible light passes through the specimen and then through glass lenses.The discovery and early study of cells progressed with the invention of microscopes in 1590 and their improvement in the 17th century.All cells are related by their descent from earlier cells.Ĭoncept 6.1 To study cells, biologists use microscopes and the tools of biochemistry.The cell is the simplest collection of matter that can live. ![]() ![]() Even in multicellular organisms, the cell is the basic unit of structure and function.
