  • whats biology

    the study of life which uses systematic and logical processes

  • whats life

    No single definition to define it instead based on properties• Lots of variation in the world• Organisms ranging from single celled to multicellular

  • whats the 7 properties of life?

    order

    reproduction

    growth n development

    response to environment

    energy processing

    regulation

    evolutionary adaption

    ORGRERE

  • defining life

    defined by the parts and process of living things/ composed of cells/ cell regulates its internal environment, takes in and uses energy, and responds toits environment/ cells make new cells/ Life may be unicellular or arrange themselves into multicellular organisms

  • whats nomenclature?

    naming of all forms of life, which each organisms is givin 2 part latin name

    Genus (capital letter) followed by species(lower case letter)•

    Italics or underlined

    Homo sapians

  • whats taxonomy

    the classification of organisms

  • name smallest to largest classification

    species-genus-family-order-class- phylum-kingdom-domain

  • domain

    Highest and most general taxonomic rank

  • kingdom

    Groups organisms that share fundamental structural, cellular and nutritional characteristics

  • phylum

    Organisms that share major evolutionary lineage

  • class

    Organisms that share a more common recent ancestor

  • order

    Groups together multiple families

  • family

    Groups together multiple genus

  • genus

    Multiple closely related species

  • species

    Most specific, only one particular species

  • 3 domain present on earth

    domain bacteria - domain archaea - domain eukarya

  • domain bacteria

    Microscopic organisms

    Most are single celled

    All cells have a very simple organization

    Cause infections

    Live in the soil, air, water, etc.

    Also found in humans gut

    3 basic shapes: coccus, bacillus and spiral

    tiny cells which most measure between 0.5 and 5 microns

    cause infections in humans

  • domain archaea

    Appear similar to bacteria

    Microscopic single celled organisms

    Simple organization within each cell

    DNA sequencing shows bacteria and archaea are not closely related

    Often live in the most extreme environments on Earth Salty lakes, hot springs, etc.

    No archaea has ever been shown to cause infection

  • domain eukarya

    All organisms with complex cells are in this domain

    Broken into 4 major kingdoms 1. Protists, Single celled organisms (ex. Amoeba)

    2. Plantae, Plants produce food using photosynthesis

    3. Fungi, Decompose organic wastes and absorb the nutrients

    4. Animalia, Obtain food by eating other organisms
