  1. Do Now: • In your binder, in your notes, put the date on the right margin of your paper and answer the following: • What are the levels of classification in order? (hint- there are 8 words) • What is the scientific name for humans?

  2. 3 Domains Domain is the largest classification group.

  3. 3 Domains • Eukarya: has a nucleus – some are multicellular, some single • Autotrophs & Heterotrophs • Archae: no nucleus – one celled- live in extreme environments • Bacteria: no nucleus- one celled- live in many environments

  4. Archae In 1983, scientists took samples from a spot deep in the Pacific Ocean where hot gases and molten rock boiled into the ocean from the Earth’s interior. To their surprise they discovered unicellular(one cell)organisms in the samples. These organisms are today classified in the domain, archae (archaebacteria).

  5. Archae. Archae are found in extreme environments such as hot boiling water and thermal vents under conditions with no oxygen or highly acid environments.

  6. bacteria They are the kinds of bacteria found everywhere and are the ones people are most familiar with. Bacteria are classified in their own domain because their chemical makeup is different.

  7. Using a life science text book, use the table of contents or the index to find the page with Autotrophs and Heterotrophs.(Hint: the glossary will not give you enough info!)With the people at your table, make a Venn diagram comparing the similarities and differences of Autotrophs and Heterotrophs. Do not forget to write on your paper what page you found your info on. EVERYONE needs to write!

  8. Autotrophs and Heterotrophs - SimilaritiesFollowing are the similarities between autotrophs and heterotrophs. Have a look at them: Autotrophs, as well as heterotrophs, are living things and both are part of some ecosystem. The autotrophs and heterotrophs, together form various trophic levels in the food pyramid Both require sunlight and water to live and obtain energy by conversion of chemical molecules. Autotrophs and Heterotrophs - DifferencesThe main difference between autotroph and heterotroph is that autotrophs can synthesize their own food, whereas, heterotrophs cannot. Most autotrophs contain the pigment chlorophyll, that plays a key role in synthesis of food. Chlorophyll is absent in almost all heterotrophs. Autotrophs obtain energy by converting inorganic raw materials into organic compounds, whereas, heterotrophs convert complex organic compounds into simpler ones to obtain energy.

  9. 4 Kingdoms of the Eukarya Domain

  10. The Four Kingdoms • Protista single celled, nucleus • Fungi single or multicellular, absorb food • Plantae multicellular producers • Animalia multicellular consumers

  11. Protists Slime molds and algae are protists. Sometimes they are called the odds and ends kingdom because its members are so different from one another. Protistsinclude all microscopic organisms that are not bacteria, notanimals, not plants and not fungi. Most protists are unicellular. You may be wondering why those protists are not classified in the Archae or bacteria domains. It is because, unlike bacteria, protists are complex cells.

  12. They can be divided into 3 types: animal-like protozoa, the plant-like algae, and the fungus-like slime moulds

  13. Fungi • Mushrooms, mold and mildew are all examples of organisms in the kingdom fungi. • Most fungi are multicellular andconsists of many complex cells. • (fungus)

  14. Fungi are organisms that biologists once confused with plants, however, unlike plants, fungi cannot make their own food. Most obtain their food from parts of plants that are decaying in the soil.

  15. Now lets see what you know….. Get with your table and see if you can correctly identify these Domains and Kingdoms: USE YOUR NOTES! Write down your ideas.

  16. Multicellular Consumers, heterotrophs j 1. What domain and what kingdom?
