Classification Group Explanations

All organisms are split into five Kingdoms:

Animal Kingdom: organisms that usually move around and find their own food.

Plant Kingdom: organisms that make their own food and do not actively move around.

Fungi Kingdom: organisms that absorb food from living and non-living things.

Protist Kingdom: organisms that have single, complex cells.

Moneran Kingdom: organisms that have single, simple cells.

 

Animal Kingdom

The Animal Kingdom is split into several Phyla. Each Phylum group contains organisms that have things in common. Below is a list of some animal Phyla:

Chordate Phylum: All the animals which have a backbone. Includes: Fish, Reptiles, Birds, Amphibians, and Mammals.

Arthropod Phylum: All the "jointed legged" animals. All of these animals have an exoskeleton, meaning the skeleton is on the outside of the body. Include: Insects, Arachnids, and Crustaceans.

Mollusk Phylum: Soft-bodied animals that sometimes have a hard shell. Includes: Snails, Slugs, Octopus, Squid, Clams, Oysters, and Mussels.

Annelid Phylum: Segmented worms. Includes: Earthworms and Leeches.

Rotifer Phylum: Tiny, microscopic animals with a wheel-shaped mouth and tiny hairs.

Nematode Phylum: Very tiny worms with no segments in their bodies. Also called Roundworms.

Tardigrade Phylum: Tiny, slow-moving animals with four body segments and eight legs. Includes Water Bears.

Cnidarian Phylum: Soft-bodied, jelly-like animals with tentacles and venom glands. Includes: Hydra, Jellyfish, Anemones, and Coral.

Echinoderm Phylum: Often spiny animals, with several "arms" reaching out from the center of its body. Includes: Starfish and Sea Urchins. We do not have these in our area!

Platyhelminthes Phylum: Soft, flat-bodied worms. Includes: Planarians and Tapeworms.

Plant Kingdom

Instead of Phyla, the Plant Kingdom is split into Divisions. Each Divsion group contains organisms that have things in common. Below is a list of some plant Divisions:

Magnoliophyta Division: All "flowering" plants. These plants have leaves, stems, and roots. After flowering, they form fruits with seeds. Includes most crops, trees, shrubs, grasses, garden plants, and weeds.

Coniferophyta Divsion: Plants that bear cones. Includes: Pine Trees and Cedars.

Pteridophyta Division: Plants that have roots and stems, but do not have flowers or seeds. Instead, they spread with spores. Includes Ferns.

Bryophyta Division: Plants with very small leaves and stems, with no roots and no flowers. Usually grow very low to the ground. Includes: Mosses.

Lycopodiophyta Division: Small plants with green, branched stems, scale-like leaves, and no flowers. Usually grow very low to the ground. Includes: Club Mosses, Quillworts, and Spikemosses.

Fungi Kingdom

Just like Plants, the Fungi Kingdom is split into Divisions instead of Phyla. Each Divsion group contains organisms that have things in common. Below is a list of some fungi Divisions:

Basidiomycota Division: Many different forms, most of which help decompose and break down wood, litter, and animal poop. Includes: Mushrooms, Puffballs, Rusts, and Jelly Fungus.

Protist Kingdom

The Protist Kingdom is split into several Phyla. Each Phylum group contains organisms that have things in common. Below is a list of some protist Phyla:

Protozoa Phylum: Tiny, microscopic organisms which reproduce by splitting in half to become two new organisms. Includes: Amoeba, Paramecium, and Sporozoa.

Euglenophyta Phylum: Tiny, microscopic organisms which have a flagella (tiny hair-like thing that helps them move through water). Some eat algae and keep it inside their bodies, using it to make food. Includes Euglena.

Moneran Kingdom

The Moneran Kingdom is split into several Phyla. Each Phylum group contains organisms that have things in common. Below is a list of some moneran Phyla:

Bacteria Phylum: These organisms are extremely important and can also be very dangerous. They live anywhere there is moisture, including inside animal's bodies. Some carry disease.

Cyanobacteria Phylum: These organisms are also known as Blue-green Algae. These algae are different from the Green Algae found in the Plant Kingdom.

Viruses

Scientists have not yet figured out where to put viruses. We have a lot we need to learn about them. They do not currently belong in one of the five Kingdoms.
