The 5 Kingdoms in Classification | Evolution | Biology | FuseSchool The classification system organises species into domain, kingdom, phylum, class, order, family, genus and finally species. ‘Kingdom’ is the second highest rank below the rank of domain in this sequence of classification. It helps us to group, or classify, species into different families so we can see how closely or not they are related. Classification attempts to impose a hierarchy on the complex and dynamic variety of life on Earth by describing how different species group together, and how related they are to one another or not. There are 5 kingdoms: animals, plants, fungi, prokaryotes and protoctists. Each kingdom has characteristic features so that an organism can easily be assigned to one of the kingdoms. Animals are eukaryotic, multicellular and have no cell walls. They develop from a blastocyst (which is part of embryo development). They have both nervous and hormonal control systems. They are heterotro
