Domains and Kingdoms

3 Domains : 

3 Domains Archaea Bacteria Eukarya

Words to know before we start… : 

Words to know before we start… 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.

Domain Archaea : 

Domain Archaea 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

Domain Archaea : 

Domain Archaea Live in extreme environments Muddy swamps Cow intestines Deep ocean vents Geysers

Domain Bacteria : 

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

Ways bacteria affect you! : 

Ways bacteria affect you! Cause : Acne Cavities Body Odor Diseases – Strep Throat, Pneumonia, food poisioning Make foods you eat Yogurt

Bacteria that are helpful : 

Bacteria that are helpful 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

Bacteria that cause disease : 

Bacteria that cause disease Streptococcus Bacteria – causes Strep throat Salmonella bacteria – causes food poisoning Bacterial Pneumonia Streptococcus pneumoniae

Domain Eukarya : 

Domain Eukarya Eukaryotes – have a nucleus and membrane bound organelles Single and multicellular organisms Divided into four kingdoms

Kingdom Protista : 

Kingdom Protista 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

Kingdom Protista : 

Kingdom Protista Animal-like protists Move Unicellular Take in food – consumers Classified by how they move Cause many diseases Paramecium Amoeba

Kingdom Protista : 

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

Kingdom Protista : 

Kingdom Protista Fungus-like Protists Have cell walls Heterotrophic –must take in food Water molds, slime molds and mildew

Kingdom Protista : 

Kingdom Protista Group of misfits –don’t belong to other kingdoms

Kingdom Fungi : 

Kingdom Fungi Gills Cap Stem

Kingdom Fungi : 

Kingdom Fungi 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

Kingdom Fungi : 

Kingdom Fungi

Kingdom Plantae : 

Kingdom Plantae

Kingdom Plantae : 

Kingdom Plantae 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

Kingdom Animalia : 

Kingdom Animalia 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

Kingdom Animalia : 

Kingdom Animalia Invertebrates – Don’t have backbones Insects Seas stars Sponges Jellyfish Worms Mollusks – snails, clams, octopus Insects

Kingdom Animalia : 

Kingdom Animalia Vertebrates – Have backbone Fish Amphibians Reptiles Birds Mammals
