  1. Chapter 1 Classification

  2. One cell or more? • The six Kingdoms are classified according to how many cells the organisms have. • All plants and animals are multi cell organisms.

  3. The numbers • About 10,000 new organisms are discovered each year. • 85% of all animals are insects and spiders. • What do you think most of those 10,000 new organisms discovered each year will probably be? An Arthropod!

  4. What’s makes a Species so special? • A species consists or organisms that are very similar to each other. Members of the same Species can mate with each other and have offspring that can also produce offspring.

  5. Adaptation • Adaptation is a characteristic that allows an organism to to survive and reproduce in its own environment. • Examples include: A snail’s hard shell that helps protect its soft body. A cactus plants spiny leaves that help it hold more water.

  6. Eat or be Eaten • Animals get energy by eating other organisms. • Plants get energy by being able to produce their own food.

  7. EW! • Archaebacteria (I like to call it EXTREME bacteria) live in places that most other life cannot like very hot water (think hot springs) or water that is way too salty. • Eubacteria live in common places like your body and everywhere else that is not “extreme”.

  8. Protists • Plant like protists produce their own food like a PLANT! (NO FAIR!) • Animal like protists consume other organisms to get energy

  9. The meaning of life • Bio mean life, so the BIOSPHERE is the system that contains all life on earth.

  10. Sorting it all out • When a scientist discovers a new organism, they study it and classify it by • How many cells it has (one, or more than one) • How they get energy (make it or get it) • How they reproduce

  11. Where’d they go? • Scientists BELIEVE (that means this is a theory) that 99 % of all species that have ever lived are no longer in existence.

  12. Webby world • Mushrooms have hyphae that is like a spider’s web. They can grow very large, and it takes in nutrients for the fungus (mushroom). You’ll likely find them in moist, dark places.

  13. Take it from the top • Kingdom-Largest variety and number of organisms • Phylum • Class • Order • Family • Genus • Species-Smallest variety of organisms • Remember: King Phillip Came Over For Good Spaghetti

  14. Carry me away • Plants are divided into vascular (tubes) and non vascular (no tubes) • I vascular plants, nutrients are carried through the tubes • In non-vascular plants, nutrients are absorbed from cell to cell in a very slow process.

  15. Is it or isn’t it? • We all are familiar with typical seed plants, but did you know that cones contain seeds too? • Gymnosperm seed plants like fir and evergreen tree do no produce flowers. • Angiosperms are flowering seed plants.

  16. Back to back • Which Phlyum contains animals with backbones? CHORDATA!
