Name: Horticulture 232 Exam I 2001 IMPORTANT INSTRUCTIONS: Please read the entire exam prior to answering any questions. Please fill in each blank as directed. Illegible answers will be counted as incorrect. Please work independently. You may not use notes. Thought for the day: If folks only knew! ….how many hours of thinking, hours of digging, days of sunshine, weeks of coaxing dozens of headaches, pounds of fertilizer, bushels of rich soil, gallons of water and hundreds of backaches it takes--to produce a pretty flower! Modena Seed Company, San Francisco, CA Section I A. 가 Points Introduction to Systematics 験榼馅㉝淎ଷ 낕帒夯ਖ 㞦쐬띥탒ⱸ蜩쪸묎懕(2 words) is the science of identifying, naming, and classifying all plants. It is a challenging field of study. B. Specific sources of scientific information regarding the systematics of a particular taxon are bibliographies, indexes, guides, and comprehensive works of broad scope. Monographs are comprehensive taxonomic treatises that synthesize all the known information about a group of plants and the term __________that refers to a published inventory of all plants growing in a geographical or political area. C. There are five objectives of Plant Taxonomy. Use Single words. 1. To ________________the world's ___________ 2. To provide a method for __________________ and __________________ 3. To produce a ______________ and_____________ system of classification 4. To demonstrate _______________implications of plant __________________ 5. To provide a single __________, scientific name for every group of plants in the world D. There are three 'phases' of plant systematics: 1. Exploration and discovery phase better known as __________taxonomy 2. Synthesis phase where classification based on _______________is developed 1 3. Experimental phase is the combining of data for interpretation in ______________and phylogenetic terms. 2 Section II.
