PLANT CLASSIFICATION Objective: Students will be able to know how to classify a plant and be able to create their own plant using the correct classification
How has plant classification evolved? • Common name insufficient • Need for uniform and internationally acceptable system
How can plants be classified? • Climate • Seasons • Edible parts • Usage • Foliage • Flowers • Growth habits • Life Cycle
WHO WAS FIRST TO CLASSIFY PLANTS? • Carolus Linnaeus (1707-1778) system led to modern taxonomy • Modern scientific naming/classification grouped by taxa based on physical characteristics
7 CATEGORIES FOR CLASSICATION • Kingdom • Division or Phylum • Class • Subclass • Order • Family • Genus • Species
Kingdom • The start of classification • 5 kingdoms • Animalia • Plantae • Fungi • Protista • Archaea • Bacteria
Phylum or Division • Plantae Kingdom is divided in to Phylas • 10 plant phylas • Non-vascular (moss): Bryophytas, Hepaticophyta, Anthocerophyta • Vascular (ferns): Pterophya, Lycophyta, • Gymnosperms (trees no showy flowers): Coniferophyta, Cycadophyta, Gnetophyta, and Ginkophyta, • Angiosperms (flowering): Anthophyta
CLASS AND ORDER • No rules for plants
FAMILY • Latin names • Names give clues to appearance • May also clue characteristics, habitat, person named for, etc.
GENUS AND SPECIES • Two-word (binomial) name • First name – genus; Second name – species • Abbreviated name of scientist who named plant • Example: “L.” means Linnaeus
Genus (generic name) always capitalized • Species (specific epithet) never capitalized • Except may be capitalized if a person’s name • Either underlined or italicized • Authority name is never italicized • Listings of several plants in same genus: • Example- • Acer rubrum (Red maple)
MORE RULES • “sp.” or “spp.” stands for species • “var.” from Latin varietas, “variety” • “cv.” from cultivated variety • Indicates exact species is not known for the genus being considered • “sp.” “spp.” “var” or “cv” never underlined or italicized
PLANT NAME EXAMPLES • Plantae Gymnosperm Alnus Alinus glutinosa- Alder, Common alder • Plantae Gymnosperm Malus Maclura pomifera- Apples, Osage apple • Plantae Gymnosperm Fraxinus Acer negundo- Ash, Black ash
Assignment • You will create your own plant • You need to have the following: • Kingdom • Division or Phylum • Class • Order • Family • Genus • Species
You will need to have a drawing of your flower • All names need to be in Latin, expected your name if you use it.
