Cambridge IGCSE Biology, topic 1
Characteristics and classification of living organisms
All living things share seven characteristics, and biologists use shared features to sort organisms into groups. This topic covers how those groups are defined and named, how a dichotomous key identifies an organism, and the features used to place organisms into kingdoms and smaller groups.
