Scientists classify organisms into large groups called kingdoms. Living things in each kingdom share basic characteristics or traits. An organism with a nucleus could belong in the animal, plant, fungus, or protist kingdom. Organisms without a nucleus are members of either the ancient bacteria or true bacteria kingdom. Members of the fungus kingdom absorb food. Organisms from the fungus kingdom cannot move. Another group of organisms that cannot move belong to the plant kingdom. Members of the animal kingdom are made up of many cells. They move from place to place and cannot make their own food. We are members of the animal kingdom.
