The Diversity of Living Things Most scientists classify organisms into six kingdoms based on different characteristics. Most scientists classify organisms into six kingdoms based on different characteristics. All organisms are made up of cells and undergo all of the requirements of life. All organisms are made up of cells and undergo all of the requirements of life.

Bacteria Bacteria are microscopic, single-celled organisms that usually have cell walls, but no nuclei and reproduce by dividing in half. Bacteria are microscopic, single-celled organisms that usually have cell walls, but no nuclei and reproduce by dividing in half. There are two kingdoms of bacteria: There are two kingdoms of bacteria: Archebacteria (found in harsh environments) Archebacteria (found in harsh environments) Eubacteria (most common) Eubacteria (most common)

Bacteria Some bacteria break down the remains and waste of other organisms and return nutrients to the soil. Some bacteria break down the remains and waste of other organisms and return nutrients to the soil. Bacteria also live within many organisms and help with their life processes.

Fungi A fungus (plural, fungi) is an organism whose cells have nuclei, cell walls and no chlorophyll. A fungus (plural, fungi) is an organism whose cells have nuclei, cell walls and no chlorophyll. A mushroom is the reproductive structure of a fungus. The rest of the fungus is a network of fibers. A mushroom is the reproductive structure of a fungus.

Fungi All fungi play an important role in decomposing other organisms and cycling materials through the environment. All fungi play an important role in decomposing other organisms and cycling materials through the environment.

Protists Protists are a large group of organisms that can appear to be like animals, plants, or even fungi. Protists are a large group of organisms that can appear to be like animals, plants, or even fungi. Algae is the most important protist from an environmental view. They form the base of most aquatic food chains. Algae is the most important protist from an environmental view. They form the base of most aquatic food chains.

Plants Plants are many-celled organisms with a nucleus and cell wall that make their own food through photosynthesis. Plants are many-celled organisms with a nucleus and cell wall that make their own food through photosynthesis. Plants release oxygen and create sugars that many other organisms depend on.

Animals Animals cannot make their own food, have a nucleus, no cell wall, but most are multi-cellular. Animals cannot make their own food, have a nucleus, no cell wall, but most are multi-cellular. Animals are very diverse and depend on other kingdoms for survival. Animals are very diverse and depend on other kingdoms for survival.
