6 Kingdoms of Living ThingsArchaebacteriaEubacteriaProtistaFungiPlantaeAnimalia
Domain Archaeaor Kingdom Archaebacteria Prokaryote unicellular Often do not need oxygen Live in harsh environments; classified base on where they live (such as thermal vents deep in ocean, salt-lakes, acidic environments, some even in ice!)
Domain or Kingdom: BacteriaProkaryoteunicellularOften do need oxygenLive and feed by decomposing other cells.Some can do photosynthesis.Cell walls made of peptidoglycan.video
Baceria Shapes1. Bacilli: - Rod-shaped2. Cocci: - Spherical (round like a coconut)3. Spirilla: - Long and spiral shaped.
Heterotrophic Bacteria1. Free-living consumers: E. coliAzobacter converts initrogen into ammonium, making it available for plant use; E. coli lives in your colon, feeds on your waste and makes vitamin K for you.2. Parasitic: Always needs an organism to get food or shelter (host): Impetigo is caused by strains Staphylococcus aureus or Streptococcus pyogenes.3. Decomposers: Pseudomonas bacteria in the soil recycles dead plants and animals by turning them into minerals and nutrients that plants and microbes can use.
Autotrophic Bacteria Producers -> Use sunlight to make food and are often green. Example: Cyanobacteria: Blue- green algae Lives in water Has chlorophyll (green pigment for photosynthesis) Some others have blue or red pigment.
Domain EukaryotaEukaryoteUnicellular or multicellularIncludes Kingdom Animalia, KingdomPlantae,Kingdom Fungi and Protista.
Protist KingdomsEukaryoteUnicellularHeterotroph or AutotrophNo cell walls in Protozoa
Protista includes Protozoa of 4 main groups:classified based on movement
Protista includes several types of Algae and Seaweedclassified based on chemical criteria (PS pigments)
Kingdom PlantaeEukaryotemulticellularAutotrophs: PhotosynthesisStrong cell walls made of cellulose
4 Main Divisions of Plants
Kingdom FungiEukaryoteMulticellular or possibly unicellularHeterotroph: absorb nutrients fromdecomposing organismsCell walls made of protein (chitin), notcellulosevideo
Lytic Cycle more of their kind.Process used by virus using a cell to make
Are virus alive? Don’t eat, grow, or break down food. They are not made of cells. They need a host cell to reproduce.There is no cure, only a treatment.Antibiotics DO NOT kill virusesAntiviral medications only stop viruses fromreproducing.
