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 ( ) 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.
