  1. Classifying Plants and Animals Unit 7

  2. Essential QuestionHow do scientists classify animals?

  3. Animals Vocabulary: classify - to sort into groups according to similar characteristics

  4. Classification of Organisms • classification—to group based on attributes/traits • Shape of teeth • Skeleton bones • Digestive systems • classification system—helps scientist find, organize, and share information --There are seven levels of the classification system. • kingdom—the largest group

  5. The Classification System • Kingdom ------- King • Phylum ------- Phillip • Class ------- Came • Order ------- Over • Family ------- For • Genus ------- Good • Species ------- Spaghetti

  6. How do Scientists Classify Organisms? 5 Kingdoms • Animal • Plant • Fungi • Protist • Moneran

  7. Animals invertebrates - animals without backbones The mollusks are a more complex invertebrate. They include soft-bodied animals such as the octopus and squid. Another group of invertebrates is called echinoderms. They include sea stars, sand dollars and sea urchins. The largest group of invertebrates are the arthropods. They have jointed legs and have two or more body segments. They have their skeleton on the outside of their body. They include crustaceans (crabs, lobsters and shrimp) and insects. Spiders are arthropods but aren’t insects, they are classified as arachnids.

  8. Animals • vertebrates - animals that have a backbone. There are five: mammals, birds, reptiles, amphibians, and fish • Vertebrate bodies are more complex than invertebrate bodies.

  9. Mammals are animals that breathe with lungs, feed their young milk, are warm-blooded, have fur or hair, their young are born alive, and most live on land.

  10. Reptiles are animals thatbreathe with lungs, are cold-blooded, have dry, scaly skin, live on land, most have teeth, and their young are hatched from eggs.

  11. Amphibians are animals that have moist skin and no scales, most begin life in the water, but live on land as adults, adults breathe with lungs, are cold blooded, young are born from eggs (metamorphosis).

  12. Fish are animals that live in water, have hard scales and gills to breathe, most are cold-blooded, and their young are hatched from eggs.

  13. Birds are animals that havefeathers, are warm-blooded, hatched from eggs, and live on the land.

  14. Essential QuestionHow do scientists classify plants?

  15. Plants Vocabulary: vascular plants– plants that have tubes that take in water and nutrients. These tubes are in roots, stems, and leaves. Redwood trees can be found in California.

  16. There are two types of vascular tissue: • xylem – carries water and nutrients from roots to other parts of a plant. You can tell the age of a tree by counting the rings of xylem. • phloem – carries food from leaves to the rest of the plant.

  17. Vascular plants grow from seeds • Plants classified as gymnosperms produce seeds that are inside a cone. • Plants classified as angiosperm have • seeds that are encased in a protective • covering such as fruit.

  18. vocabulary • nonvascular plants – plants that don’t have tubes. Water must soak into the plants and travel slowly from cell to cell.

  19. Nonvascular Plants • Nonvascular plants absorb water and nutrients from their surroundings. • Water carries food and nutrients directly from cell. • Because of this, the plants cannot grow very tall.
