  1. Ordered Structure for the Classification of Organisms

  2. Classification • Taxonomy- the study of how scientists classify organisms. • Modern classification systems uses a series of levels to group organisms.

  3. Classification • An organism is placed into a broad group and is then placed into more specific groups based on its structure. • The levels of classification, from broadest to most specific, include:

  4. Classification • The more classification levels an organism shares with another, the more characteristics they have in common.

  5. 5 kingdoms- Monerans, Protists, Fungi, Plants, Animals Organisms are place in kingdoms based on their ability to makefood and the number of cells in their body. Levels of Classification:Kingdoms

  6. Phylum (pl. phyla) • In the plant kingdom, phyla are sometimes referred to as divisions. • Plants are divided into 2 groups: vascularand non-vascular. • There are 35 phyla in the animal kingdom. These are divided into vertebrate and invertebrate.

  7. Class, Order, Family • These levels become even more specific. • They include fewer organisms that have more in common as they go down the levels.

  8. Genus • Contains closely related organisms • The genus is used as the first word in an organism’s scientific name.

  9. Species • Consists of all the organisms of the same type which are able to breed and produce offspring of the same kind. • The species is used as the second word in the scientific name.

  10. Remember this… • King Phillip came over for good spaghetti. amily pecies rder enus lass ingdom hylum

  11. Scientific Name • The scientific name of an organisms is made up of its genus and species. • It is written in italics (Genus species) with the genus capitalized. • Ex. Canis lupus is the scientific name for the wolf. • Ex. Pinus taeda is the scientific name for a loblolly pine.

  12. The Five Kingdoms • Monerans (bacteria) • Protists • Fungi • Plants • Animals

  13. Monerans • Single celled organisms • Prokaryotic (no nucleus) • Some are heterotrophic, some are autotrophic • Bacteria fall into the Moneran Kingdom

  14. Protists • Protists are mostly single celled organisms (unicellular) but some protest are multi-cellular • Protists cells are eukaryotic (have a nuclei • Some are animal-like (heterotroph- need to eat other organisms) and some are plant-like (autotroph- use sunlight to produce food).

  15. Fungi ● Almost all fungi are multi-cellular organisms. ● Fungi cells have nuclei (eukaryotic). ● Fungi do not move to get food, but they do need to absorb nutrients from other organisms (either living or dead).

  16. Plants ● All plants are made of many eukaryotic cells. ● Plants are autotrophs - they use sunlight to make their food

  17. Animals ● Animals are multi-cellular organisms. ● Animal cells have nuclei (eukaryotic). ● Almost all animals move to get food. Animals are heterotrophs - they eat other organisms to get energy
