WARM UP “Do not look back and ask why, look forward and ask, why not?” Write two or three sentences about what this means to you.

Plant Classification Biology II

Taxonomy - Science of Classification Grouping based on similarity (more similar groups as you work down) Kingdom Phylum Class Order Family Genus Species

Phyla of Plants (Basic Similarities) Bryophytes Nonvascular Spores Mosses

Phyla of Plants (Basic Similarities) Ferns Vascular Spores Whisk ferns Club mosses Horsetails

Phyla of Plants (Basic Similarities) Gymnosperms Vascular Seeds Cones Conifers Cycads Gingko Gnetophytes

Phyla of Plants (Basic Similarities) Angiosperms Vascular Seeds Flowers

Dichotomous Keys Step by step identification guide Choose one of two traits at each step Doublets Need to know traits/terms

Dichotomous Keys

Plant Traits and Terms (for keys) Coniferous: Needles, evergreen Deciduous: Broadleaf

Plant Traits and Terms (for keys) Branch Organization Needles Single Clustered

Plant Traits and Terms (for keys) Branch Organization Leaves Alternate Whorled Opposite

Plant Traits and Terms (for keys) Deciduous leaf type Simple leaf One per bud Compound leaf Many “leaflets”, one bud Pinnate (long) Palmate (like fingers)

Plant Traits and Terms (for keys) Leaf Shape

Plant Traits and Terms (for keys) Leaf Edge Entire Toothed Rounded Lobed

Binomial Nomenclature After keying or dividing taxa, you need to name each unique thing Organisms named with genus and species Ursus americanus Developed by Carolus Linnaeus

WRAP UP List 3 categories you could use to key out the different types of shoes in the classroom.

Name at least 6 different types of plants. WARM UP Name at least 6 different types of plants.

WRAP UP Define taxonomy in five words or less. Compare and contrast mosses and ferns.
