Scientific Classification

1. Scientific Classification Objective 3.03 Discuss floriculture and landscape plants.

2. Scientific Classification of Plants • Taxonomy- the science of classifying and identifying organisms such as plants

3. Scientific Classification • Scientific names are necessary because the same common name is used for different plants in different areas of the world • Latin is the language used for scientific classification

4. Scientific Classification • Carlos Linnaeus • Swedish botanist • Developed the binomial system of naming plants using two Latin words to indicate the genus and the species

5. Scientific Classification • Scientific Name • First word=genus • First letter is capitalized • Second word=species • If there are additional words after the species, they indicate the variety or cultivar • Variety is var. • Cultivated variety is cv

6. Scientific Classification • Plants in the same genus have similar characteristics • Plants in the same species consistently produce plants of the same types

7. Scientific Classification

8. 4 Most Important Divisions of the Plant Kingdom • Thallophytes: algae, fungi, and lichens • Bryophytes: true mosses and liverworts • Pteriophytes: ferns, horsetails, and club mosses • Spermatophytes: seed-bearing or flowering plants • Gymnosperms: seeds are not in an ovary (cone) • Angiosperm: seeds enclosed in an ovary (flowering plants)

9. Activity • Choose 2 plants we have covered so far during Plant ID • Find out their Scientific Classification • Find the Kingdom, Phylum, Class, Order, Family, Genus, and Species • Do the plants you chose have anything in common? • CWHW Portfolio #3
