  1. Chapter 1 Classification Section 1 and Section 2

  2. Where on Earth do Organisms Live • I. Biosphere- the part of the Earth that can support living things • All organisms (2 million + 10,000 new ones a year) • Environments- desert, oceans, fields, rainforest • A. All organisms in biosphere are connected • All are made of cells ( can be one cell or more) • Have different characteristics (snail vs. horse)

  3. Adaption- • A. All organisms in the biosphere are connected • Adaptation- a characteristics that enables to an organism to survive and reproduce • Examples- Spines on cactus are modified leaves • Helps stop water loss • Protect from harsh temperatures • Thick stems store a lot of water

  4. Species • B. Species- a group of similar organisms whose members can reproduce and produce offspring that can reproduce. • Animals that look alike are not necessarily in the same species. • Example- Horses and donkeys can mate to produce a mule, but mule’s can’t reproduce

  5. Lesson 2: How do we group organisms • 1. Classification- a grouping of organisms based on similarities • Carolus Linnaeus is considered the Father of Classification- 1700’s • Grouped into two main groups- plant or animal kingdom • Each kingdom was divided into 6 smaller groups based on their features

  6. 6 levels in a kingdom • Kingdom • Phylum • Class • Order • Family • Genus • Species • King Philip Came Over For Great Spaghetti • More variety Less Variety

  7. Bacteria • II. Bacteria- not discovered until after Linnaeus created his two major kingdoms • Single Cell organisms • No Nucleus

  8. Kingdoms today • III. Today we have 6 kingdoms • A. Animals- get energy from eating other organisms • B. Plants- • Use Photosynthesis to make glucose( a sugar) from • Sunlight, carbon dioxide, and water • If we did not have plants then life on Earth would cease to exist

  9. Fungi • C. Fungi • Used to make food- cheese or medicine- pencillin • Harmful- ringworm, athlete’s foot, and plant rusts • No chlorophyll so can’t make food • Absorb food and nutrients through a membrane • Grow in damp, dark areas

  10. Protists • D. Protists • 3 types • Animal like- get energy from eating other animals • Plant like- contain chlorophyll so can make own food • Fungus like- absorb food through membrane

  11. Eubacteria • E. Eubacteria • Are everywhere • More bacteria in mouth than people in the world • Used to make yogurt • Make vitamins in your body • Make soil fertile

  12. Archaebacteria • E. Archaebacteria • Live in extreme conditions such as high salt areas or very hot water • Benn on Earth for billions of years
