Classify - GCSE Biology Definition

In GCSE Biology, to "classify" means to organise living things into groups based on their similarities and differences. Scientists use classification to understand how organisms are related to each other, and it helps us to study the vast diversity of life on Earth. For example, animals are grouped into categories like mammals, birds, and reptiles. Plants, fungi, and microorganisms each have their own groups as well. This system of classification helps make it easier to study and learn about living things, since organisms in the same group often share common traits. By classifying, we can trace how life forms have evolved and how they are connected in the tree of life.
