The classification system is the arrangement of living things, categorised by their different characteristics - an organised understanding of the natural world we live in. Recently this system has been further refined using studies of DNA. In this programme, we discuss how the classification system is organised and how scientific names are arrived at. The dichotomous keys used by biologists to classify specimens are demonstrated and the five major groups of living things are explained. An entertaining programme that explains how observed characteristics of living things are used to establish a classification system.
Plants are extremely complex and diverse - there are thousands of species. In fact, there are probably somewhere around half a million different species. And these are just the ones we know about - there are no doubt many more that haven’t been fully discovered yet! It is estimated that 1 in 5, so 20% of plant species are threatened with extinction. In order to continue studying all these plant species, we need to organise them into different groups. This is known as plant classification. Plants within a group are more closely related to other members of their own group than they are to members of another group. Just like we as humans are more closely related to the great apes than we are to other mammals.
