**__Essential Questions__**
Three Main Requirements for life 1) Living things all obtain or use energy - The process of photosynthesis (mainly plants) - The process of cellular respiration (mainly non-plants) - Chem auto trophy (eating chemicals, e.g. methane, oil, sulfur) 2) Living things all have the ability to store/transmit information - Adaptation (organism change in order to fit the surroundings) - Evolution (organism change genetically to adapt to the environment) 3) Living things have "containers" - Container = plasma membrane (usually)1232451803 Livings things all have... - DNAs - Cell-based structure - Ability to move/be in motion - Growth - Reproduction - Homeostasis - Ability to adapt/evolve - *feel free to add more if anyone have it...*1232451803 4. Why are there so many species? 5. ** **Why are only a small % of all species still present today?** Humans over-harvest, destroy habitats and pollute the environment, this accelerates the extinction of species. **6.** **How do biologists organize biodiversity?** SIX KINGDOMS 2.2.09 Biology G
 * 1. How is life defined? **
 * 2. What are the characteristics shared by living things? **
 * 3. How many species are there and how many have there been?

PROKARYOTIC Archaebacteria: unicellular prokaryotes; many live in harsh environments with extreme temperatures, anaerobic environments, and high acidity or salt content; majority are autotrophic by chemosynthesis (before lots of oxygen on earth) Eubacteria: unicellular prokaryotes; more common (effects such as tooth decay, getting sick) photosynthesis or chemosynthetic. i.e. salmonella – proteomic bacteria, strep throat etc.

EUKARYOTIC Animals: eukaryotic, multicellular, heterotrophs (eats others) cells do not have cell wall, only a cell membrane. That’s why you’re squishy not crunchy i.e. butterflies, fish, bears. Plants: eukaryotic, multicellular, photosynthetic autotrophs. Cells have a cell wall. Crunchy not squishy. i.e. grasses, cone producing pine trees etc. Protists: eukaryotes; “catch all kingdom”; mostly single celled (like amebas) but also multicellular like kelp, but lack specialized tissue. Reproduce sexually and asexually; autotrophic or heterotrophic, i.e. plasmodium is a unicellular, heterotrophic sporozoa responsible for mabrin porphyra (red algae). Fungi: eukaryotic, heterotrophs. Mostly multicellular i.e. mushrooms, yeast.

PROKARYOTE: no nucleus > all mixed up inside, no organization EUKARYOTE: nucleus, very internally organized – multicellular autotrophs CHEMOSYNTHESIS: using chemicals DOMAIN: Archaea, Eubacteria, Eukaryota **7.** **What characteristics are used in classifying biodiversity?** There are a couple ways that scientists use to classify biodiversity! They use the following techniques Morphology Molecular this is looking at the DNA and Proteins that an organism has. Fossils These are all schared charactieristics

9. How do molecular differences reveal evolutionary histories? 10. ** **What are the hallmark traits of the 3 domains and 6 kingdoms of life?**
 * 8. What is the relationship between evolution and taxonomy today?
