Identification, Variation, & Adaptation Big Ideas

8 Major Categories of Classification Species is the most specific Dear King Phillip Came Over For Good Soup

6 th Grade Review All living things are classified into taxonomic groups: the largest and broadest umbrella is the domain The 3 Domains for the Taxonomic Classification of Living Things are as follows: – Bacteria – Archaea – Eukaryota

Characteristics are used to classify organisms into kingdoms – Type of cell (prokaryotic or eukaryotic) – Number of cells (unicellular or multicellular) – Food source (autotrophic or heterotrophic) – Mode of reproduction (sexual or asexual) There are currently 6 kingdoms –The 6 Kingdoms of living things are as follows:  Archaebacteria  Eubacteria  Fungi  Protists  Plants  Animals 6 th Grade Review

Most Asexual, some Sexual ArcheabacteriaEubacteria Need to Know Decomposers, some cause disease extreme environments, old bacteria Tiny organisms, cannot be classified as fungi, plants, or animals (leftovers) mushrooms, molds, and mildew Do not move from place to place on their own Most can move for at least part of their lives

Prokaryotic Pro means NO No nucleus Eukaryotic Has a nucleus You have a nucleus and are Eukaryotic vs.

Unicellular 1-celled organism Multicellular Organisms with more than 1 cell vs.

Autotrophs Make their own energy (food) through photosynthesis Heterotrophs Eat other organisms to get energy vs.

Asexual Reproduction 1 parent Uniform offspring Sexual Reproduction 2 parents Diverse offspring vs.

Taxonomy Classification Taxonomy – the science of classifying (naming) organisms Binomial Nomenclature – developed by Carolus Linnaeus – 2-word naming system (genus and species) Examples: – Felis concolor (mountain lion) – Ursus arctos (brown bear) – Homo sapiens (humans) – Panthera leo (lion) – Panthera tigris (tiger) Recognize and properly write a scientific name: Homo sapiens, or Homo sapiens, or H. sapiens – 1st word is Capitalized –Genus – 2nd word is lowercase —species – Underline – Italicize – Abbreviate the genus (first name) (P. tigris or P. leo)

1AIf the edge of the leaf has no teeth, waves, or lobes Go to 2 1BIf the edge of the leaf has teeth, waves, or lobes Go to 3 2AIf the leaf has a single bristle at its tip Shingle Oak 2BIf the leaf has no single bristle at its tip Go to 4 3AIf the leaf edge is toothedLombardy Poplar 3BIf the leaf edge has waves or lobes Go to 5 4AIf the leaf is a heart-shaped leaf with veins branching from the base Redbud 4BIf the leaf is not heart shapedLive Oak 5AIf the leaf edge has lobesEnglish Oak 5BIf the leaf edge has wavesChestnut Oak

Adaptations Explain how each adaptation is used by an organism to enhance its survival… Hollow bones Dense bones Xylem Plant storage bulb Pholem Gills Lungs Migration Hibernation

Natural Selection vs. Selective Breeding View BrainPop Natural Selection through 2:48

Natural Selection Changes in genetic traits that occur over many generations due to environmental factors for survival or reproduction – Temperature, rainfall, predator-prey, attracting mates

Natural Selection Galapagos Medium Ground Finch Now several species of finch because the variety of food sources found in different areas

Peppered Moths During the Industrial Revolution trees were covered with soot from smoke Natural Selection ….the result

the process of HUMANS choosing specific plants or animals to breed for desirable genetic traits Domesticated animals Crops Selective Breeding

Domesticated animals are bred for…. Mild temper Color Speed Selective Breeding

Farm animals are bred for… Lay most eggs More meat Produce more milk Mild temper No horns Strength

Plants such as fruits, vegetables, and garden flowers are bred for… To produce more crop To produce bigger crop Resistant to pests and diseases Drought-resistant Selective Breeding
