Order Of Magnitude - GCSE Biology Definition

'Order of magnitude' is a way to describe the size or amount of something by comparing it in powers of ten. In GCSE Biology, it helps you understand the scale of biological measurements, such as the size of cells or molecules. For example, if one object is 10 times bigger than another, it is one order of magnitude larger; if it is 100 times bigger, it is two orders of magnitude larger. This makes it easier to compare and understand large differences in size in biology.
