Chapter 2 Tree Identification Flashcards
Taxonomy
Science that studies the description, denomination, and classification of living organisms based on their similarities and differences. Contrast with morphology.
Kingdom
Primary taxonomic group, separating plants from animals
Division
Phylum. Taxonomic group below the kingdom level but above the class level.
Phylum
Primary taxonomic group within a kingdom. Division.
Vascular plants
Plants with xylem and phloem elements for conducting water, nutrients, and photosynthesis.
Angiosperm
Plant with seeds borne in an ovary. Consists of two large groups: monocotyledons (grasses, palms, and related plants) and dicotyledons (most woody trees, shrubs, herbaceous plants and related plants). Contrast with gymnosperm.
Gymnosperm
Plants with exposed seeds, usually within cones. Contrast with angiosperm. Ginkgos and conifers. Come bearing plants.
Class
Taxonomic group below the division (phylum) level and above the order level.
Dicotyledon
Plant with two cotyledons in its embryo; netted or palmate leaf veins; and flowers with three, four, or five petals, or petals in multiples of these numbers. Contrast with monocotyledons.
Most common tree species.
Monocotyledons
Plant with an embryo that has one seed leaf (cotyledon). Examples are grasses and palms. Contrast with dicotyledon.
Conifers, bananas, palms, lilies, orchids
