TAXONOMY

Taxonomy. is a branch of science that deals with the classifications of living things

Carolus Linnaeus 1753 Father of Taxonomy

Five Kingdom System Animalia Plantae Fungi Protista Procaryote/Monera

Monera (Bacteria)

Fungi 1.Absorptive Chemoheterotrophs 2.Decomposers

Protista 1.Unicellular 2.Autotrophic or Heterotrophic Examples: Amoeba Paramecium, Euglena

The 5 Classes of Vertebrates

Reptiles They breathe with lungs. They are cold-blooded. Their bodies are covered with dry scales. They lay eggs. Black snakes, Bearded dragons, Turtles, Crocodiles, and Alligators are reptiles.

Reptiles Geckos and Skinks are unusual reptiles. Frogs and Toads are non examples.

Amphibians They breathe with lungs and gills. They are cold blooded. Their skin is smooth and moist. Their birth of young is eggs. The examples are frogs, salamanders, newt, and mud puppies.

Amphibians African clawed frog is a unusual example. The lizard is a non-example.

Fish They breathe with gills. They are cold blooded. Their skin is covered with scales and bony plates. They lay eggs and have live births. An example of a fish is a gold fish and sharks.

Fish A unusual example would be a sea horse and an eel. A non-example would be a dolphin, whale and starfish.

Mammals Mammals breathe with lungs. They are warm blooded. They have hair/fur. Most give birth to live young. Some examples are bears, lions, tigers, and people. Some unusual examples bats, whales, and dolphins

Mammals Non-examples are sharks and penguins.

Birds Birds breathe with lungs. They are warm-blooded. They are covered with feathers. They give birth to eggs. Examples of birds would be a red bird, hawk, and chicken. Some unusual birds are the ostrich, flamingo, and penguin.

Birds Some non-examples are the bat and the dragonfly.

Invertebrates 8 Phyla of Invertebrates

Phylum Porifera (sponges) asymmetrical Body has canal and pores sessile (attached to object, cannot move)

Phylum Coelenterata (stinging cell) Stinging cells and hollow bodies tentacles that surround a mouth Examples: Jellyfish sea anemone coral hydras

Phylum Echinodermata (spiny skin) 5 part body spines Tube Feet (with Suctions) Examples Sea star or starfish Sea urchins, sand dollars

Phylum Platyhelminthes (Flatworm) flattened body One body opening Many are parasites, some are Free- Living Can regenerate Examples: Planaria, Tapeworm

Phylum Nemathelminthes (Nematoda/roundworm) Round bodies with pointed ends Males & females are separate Examples: Hookwork Ascaris

Phylum Annelida (segmented worm) Body divided into segments (with setae) Most are hermaphrodites & free living Examples Earthworms Ragworms Leeches

Phylum Mollusca (soft-bodied) Soft body usually protected by a shell Body covered by mantle Have muscular foot Most have separate sexes Examples: snails, slugs, octopus, cuttlefish, chitons, tusk shells, oysters, clams, and squids

Phylum Arthropoda (joint-legged) Jointed appendages Segmented bodies Exoskeleton that sheds by molting Head, thorax, abdomen are main parts Some separate sexes, hermaphrodites, parthenogenesis Examples: scorpion, caterpillar, shrimp, lobster, crabs, insects

Plantae 1.Multicellular 2.Photoautotrophs

Classifying Plants

Plants Plants do not have fur, scales, or blood, so how are they classified? Like animals, plants are divided into two main groups. Then these two groups are divided into smaller groups. The ways that plants get their food and the ways that they create new plants will help you classify them.

Who studies plants? A botanist is a scientist who specializes in the study of plants. They classify plants based on their characteristics (vascular and nonvascular). You could call them “Plant Explorers.”

How are they classified? One way that plants can be classified is by how they carry water. Plants can either be Vascular or Nonvascular. Vascular means “having tubes”Vascular means Nonvascular mean “not having tubes”Nonvascular mean

Vascular Plant Plants that have tubes, roots, stems, and leaves. These plants stand up tall.

Why are these trees vascular? They have tubes, roots, stems, and leaves. They also stand up tall.

More Vascular PlantsPlants

Plants that do not have tubes, roots, stems, or leaves. These plants soak up water and food from the soil, like sponges. They are also much smaller than vascular plants. Nonvascular Plant
