The Five Kingdoms of Organisms The different characteristics of organisms allow them to be classified into 5 kingdoms. Plant Kingdom Sun Plants contain and are autotrophs because they make their own food by photosynthesis. Plants are also multicellular (made of many cells) and have rigid cell walls made of cellulose. Animal Kingdom Animals are multicellular, but don't have cell walls or chlorophyll. Animals are heterotrophs because they can't make their own food. They get their food by moving around and eating and digesting other organisms. Fungi Kingdom Fungi are multicellular, have a cell wall, but don't have chlorophyll. Fungi are saprophytes and they feed on dead and decaying organisms, which they digest outside the body. Protoctist Kingdom Protoctists are unicellular (single cell) and have a nucleus. u Prokaryotes Kingdom Prokaryotes are also unicellular. There cell structure is very simple and they don't have a nucleus, e.g. bacteria.

Virusesdon't belong to any kingdom and are regarded as non-living. They show no life processessud growth, respiration or feeding. Viruses reproduce by instructing the cells they invade to make copi them —this is neither asexual nor sexual reproduction.
