Depth of fie ld is a measure of the amount of a specimen that can be in focus. Magnification and resolution are terms used frequently in the study of cell biology, often without an accurate definition of their meanings. Magnification is a ratio of the enlargement (or reduction) of an image (drawing or photomicrograph), usually expressed as X1, X1/2, X430, X1000, etc. Resolution is the ability to distinguish between two points. Generally resolution increases with magnification, although there does come a point of diminishing returns where you increase magnification beyond added resolution gain. Scientists employ the metric system to measure the size and volume of specimens. The basic unit of length is the meter (slightly over 1 yard). Prefixes are added to the "meter" to indicate multiple meters (kilo meter) or fractional meters (milli meter). Below are the values of some of the prefixes used in the metric system. kilo = one thousand of the basic unit meter = basic unit of length centi = one hundreth (1/100) of the basic unit
