PLANT CLASSIFICATION Objective Students will be able to

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.
