HS 200 Lecture Notes - Lecture 1: Vascular Plant, Gymnosperm, Plant Taxonomy
Document Summary
Hs 200 lecture 1 plant taxonomy and nomenclature. Plant taxonomy and nomenclature is based on biological, chemical, and anatomical similarities. Higher plants with roots, stems, and leaves with a system for moving materials within a plant. Gymnospermae = naked seeds exposed seeds: there are just under 700 species in gymnospermae, ginkgo and conifer are two examples, uses: pulp, paper, lumber, turpentine. Angiospermae = enclosed seeds fruit bearing: 250,000 species in angiospermae, plants have broad leaves, uses: food, fiber, beverage, paper, oils. Family a group of closely related (genera) plants, based on certain plant structures on their biochemistry. A group of plants within a family that are similar in reproduction based on reproductive organs, example: acorn. A group of plants within a genus that share similar vegetative and reproductive characteristics. Distinguishes them from all other plants in the same genus. Common names can be created by anyone, vary by region (example: bluebell, daisy)
