Classification System of Organisms Once upon a time, all living things were lumped together into two kingdoms, namely plants and animals
Plant and Animal
Animals included every living thing that moved, ate, and grew to a certain size and stopped growing. Plants included every living thing that did not move or eat and that continued to grow throughout life.
Five Kingdom Classification System
It became very difficult to group some living things into one or the other, so early in the past century the two kingdoms were expanded into five kingdoms: Protista (the single-celled eukaryotes); Fungi (fungus and related organisms); Plantae (the plants); Animalia (the animals); Monera (the prokaryotes).
Kingdoms are divided into categories called phyla, each phylum is divided into classes, each class into orders, each order into families, each family into genera, and each genus into species.
KINGDOM MONERA (monerans) - Single cell No true nucleus - prokaryote (genetic material scattered and not enclosed by a membrane) Some move (flagellum); others don't Some make their own food (autotrophic); others can't make their own food (heterotrophic) Examples - bacteria cyanobacteria
KINGDOM PROTISTA (protists) Single cell Have a true nucleus – eukaryote Some move (cilia, flagella, pseudopodia); others don't Some are autotrophic; others are heterotrophic Examples - amoeba, diatom, euglena, paramecium, some algae (unicellular), etc
KINGDOM FUNGI Multi cellular Have nuclei Mainly do not move from place to place Heterotrophic (food is digested outside of fungus) Examples - mushroom, mold, puffball, shelf/bracket fungus, yeast, etc
KINGDOM PLANTAE (plants) Multicellular Have nuclei Do not move Autotrophic Examples - multicellular algae, mosses, ferns, flowering plants (dandelions, roses, etc.), trees, etc
KINGDOM ANIMALIA (animals ) Multicellular Have nuclei Do move Heterotrophic Examples - sponge, jellyfish, insect, fish, frog, bird, man
Kingdom Phylum Class Order Family Genus Species
Phylum in Animalia Porifera (sponges) Cnidaria (jellyfish, hydras, sea anemones, Portuguese man-of-wars, and corals) Platyhelminthes (flatworms, including planaria, flukes, and tapeworms) Nematoda (roundworms, including rotifers and nematodes) Mollusca (mollusks, including bivalves, snails and slugs, and octopuses and squids) Annelida (segmented worms, including earthworms, leeches, and marine worms) Echinodermata (including sea stars, sea cucumbers, sand dollars, and sea urchins) Arthropods (including arachnids, crustaceans, millipedes, centipedes, and insects) Chordata (animals with nerve chords - this group includes the vertebrates)
Classes in Chordata
THE INSECT ORDERS ORTHOPTERA: grasshoppers, crickets COLEOPTERA: beetles LEPIDOPTERA: butterflies, moths DIPTERA: flies, mosquitoes HYMENOPTERA: ants, wasps, bees HEMIPTERA: true bugs HOMOPTERA: aphids, cicadas DERMAPTERA: earwigs ODONATA: dragonflies ISOPTERA: termites
