kingdom monera (prokaryotae)

single celled organisms without membrane-bound nucleus or organelles, heterotrophs or autotrophs, eg bateria

kingdom protista (protoctista)

simple organisms that don’t fit into the other kingdoms with membrane-bound nucleus and organelles, mainly single-celled, those that are multicellular are very simple and don’t form tissue, eg algae

kingdom fungi

mainly multicellular, heterotrophs (absorb food) have a nucleus in cells and cell walls made of chitin, reproduce asexually using spores

kingdom plantae (plants)

complex multicellular organisms, photosynthesise, have a nucleus in cells and cell walls made of cellulose, reproduce sexually and asexually, non-motile

kingdom animalia (animals)

multicellular, heterotrophic organisms (feed by ingestion), have a nucleus in cells, usually have nervous and muscular systems, reproduce sexually
