2.  Archaea  Bacteria  Eukarya

3.  Organism- a living thing.  Cell- The smallest unit that can perform all of life’s processes.  Organelles- Small bodies in a cell’s cytoplasm that are specialized to perform a specific function  Nucleus: An organelle inside a cell that contains all of the DNA and instructions for how a cell should work.

4.  Prokaryotes – no nucleus  Cell Wall  Unicellular (only one cell)  Move with flagella  Some make their own food  Some need to take in food Thermus aquaticus

5.  Live in extreme environments  Muddy swamps  Cow intestines  Deep ocean vents  Geysers

6.  Prokaryotes – Do not have a nucleus  Reproduce by fission – dividing in half  Unicellular  Cell Wall  Live everywhere  Helpful and harmful

7.  Cause :  Acne  Cavities  Body Odor  Diseases – Strep Throat, Pneumonia, food poisioning  Make foods you eat  Yogurt

8.  Used to make foods like yogurt, sauerkraut, cheese, and vinegar  Used to make medicines – antibiotics and vaccines  Help to break down wastes like garbage, sewage, and oil – called bioremediation  Help digest our food

9. Streptococcus Bacteria – causes Strep throat Salmonella bacteria – causes food poisoning Bacterial Pneumonia Streptococcus pneumoniae

10.  Eukaryotes – have a nucleus and membrane bound organelles  Single and multicellular organisms  Divided into four kingdoms

11.  Eukaryotes  Mostly single-celled (unicellular) or simple multicellular  3 Groups  Animal-like  Plant-like  Fungus-like  Group of “misfits” or odds and ends – when scientists don’t know where to put unicellular organisms placed here!  Microscopic  Live in Water

12.  Animal-like protists  Move  Unicellular  Take in food – consumers  Classified by how they move  Cause many diseases Paramecium Amoeba

13.  Plant-like Protists  Producers – make their own food  Algae are an example  Found mostly in water  Important food source for animals  Don’t move

14.  Fungus-like Protists  Have cell walls  Heterotrophic –must take in food  Water molds, slime molds and mildew

15.  Group of misfits –don’t belong to other kingdoms

16. Gills Cap Stem

17.  Eukaryotes – have nucleus  Multicellular – except for yeast  Have cell walls  Can not perform photosynthesis – no chloroplasts  Must take in food (Heterotrophs)  Molds, Mushrooms and yeast

20.  Eukaryotic – have nucleus  Multicellular  Have cell walls  Have chloroplasts -Make their own food through photosynthesis  Don’t move but respond by growing around objects, turning towards light, and growing upwards.  Live on land and water  Life on Earth dependent on plants for food and habitat

21.  Eukaryotes – have nucleus  Multicellular  No cell walls  Take in food - consumers  Usually able to move  Most have specialized sense organs to respond to environment  90% are insects

22.  Invertebrates – Don’t have backbones  Insects  Seas stars  Sponges  Jellyfish  Worms  Mollusks – snails, clams, octopus  Insects

23.  Vertebrates – Have backbone  Fish  Amphibians  Reptiles  Birds  Mammals
