The five kingdoms are:

Animalia: Animals are multicelluar. The cells have no chorophyll and are not surrounded by a cell wall. They feed from food obtained from the enviroment and digested within the body. (Heterotrophically).

Plantae: These are also multicelluar. It does have chorophyll and a cell wall. They obtain food from photosynthesis. (Autotrpohically).

Fungi: Usually Multicelluar. No Chorophyll but does have a cell wall (not made of cellulose). Feed on dead organic matter (Saprophytically)

Protoctista: Unicelluar (except seaweed). Distinct nuculeus. 

Prokaryote: Body is unicelluar. No distinct nuculeus.
