Protista eukaryotic, unicellular or multicellular, heterotroph & autotroph, most varied group, some have cell walls some do not, can reproduce sexually or asexually
Fungi eukaryotic, unicellular or multicellular, heterotrophs, decomposers, cell walls made of chitin
Plantae eukaryotic, multicellular, autotrophic, cell walls made of cellulose, reproduces sexually & asexually
Animalia eukaryotic, multicellular, heterotrophs, no cell walls, reproduce sexually
Phylogenetic tree/Cladogram a diagram that shows the evolutionary relationships & how closely or distantly related organisms are
