Chapter 1 Classification
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.
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!
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.
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.
Eat or be Eaten • Animals get energy by eating other organisms. • Plants get energy by being able to produce their own food.
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”.
Protists • Plant like protists produce their own food like a PLANT! (NO FAIR!) • Animal like protists consume other organisms to get energy
The meaning of life • Bio mean life, so the BIOSPHERE is the system that contains all life on earth.
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
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.
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.
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
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.
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.
Back to back • Which Phlyum contains animals with backbones? CHORDATA!
