Science

• Organism


  Any living thing
• Unicellular organism


  Living organism has one cell which carries out all functions necessary to stay alive
• Multicellular organism


  Living organism has many cells. Each group of cells are specialized to do certain task
• Growth


  A property where the living organism becomes larger by making new cells
• Reproduction


  A property where living organisms produce offspring that are like their parents
• Stimulus


  Any change or signal in the environment that can make an organism react
• Response


  Any action or a change in living organisms' behavior to respond to stimuli
• Autotroph


  Organisms that make their own food by themselves to get energy
• Heterotroph


  Organisms that can't make their own food by themselves and depend on others to get the food
• Homeostasis


  Stable internal conditions required for body systems to function
• Reproduction


  The process that produces more of the same kind of organisms
• Growth


  A permanent increase in size and body mass of the living organism
• Species


  A group of similar living organism that can breed and produce fertile offspring
• Organism


  Any living thing as horse, tree and bacteria
• Chemicals in living organisms

  Carbohydrates, water and lipids
• Characteristics common in all living organism

  All have cells

  All need water

  All need food
• Taxonomy


  The science that studies similarities between living organisms and classify them
• Binomial nomenclature


  A way to name living organisms by using the name of genus and species
• Domain


  The broadest level of organization in taxonomy

  
• Species


  A group of similar organisms that can mate with each other and produce fertile offspring
• Binomial nomenclature


  The scientific way to name any living organism
• Genus


  The first word in binomial nomenclature, typed starting with uppercase and italic letter
• Species


  The second word in binomial nomenclature, typed lowercase and italic letter
• Taxonomy levels in order


  • Domain - Kingdom - Phyla - Class - Order - Family - Genus - Species

  
• Hyphae


  The cells of fungi form long threadlike tubes
• How fungi obtain food

  Release enzymes through their hyphae to break down and absorb food
• Fungi roles


  Decomposers that consume dead organisms, and pathogens that attack living hosts
• Fungal reproductive structure


  Spores that produce more fungi
• Penicillium


  • A fungus that produces penicillin, an antibiotic to kill bacteria
• Host


  An organism that provides a source of energy or suitable environment for a virus to live
• Vaccine


  A substance used in vaccination that consists of pathogens
• Virus


  A non-living pathogen
• Binary fission


  The way bacteria reproduce
• Endospore


  A thick-walled shell around bacterial genetic material in harsh conditions
• Steps of viral invasion

  Virus injects genetic material into host cell

  2. Cell makes copies of virus

  3. Cell bursts, releasing many new copies of virus
• Bacterial helpful roles


  • Act as decomposers
  • Help digest butter
  • autotrophs bactiara make oxygen
• Bacterial harmful roles


  • Not provided
• Fungal Reproductive Structure


  The part of a fungus that produces spores.
• Spores


  Tiny particles that contain genetic material and can grow into a new fungus.
