2. Plant Systematics  Basic process in plant taxonomy  Cataloging  Identifying  Classifying

3. Cataloging  3 Parts in Cataloging  Naming: Uses binomial nomenclature  Describing: Looks at attributes of a plant to assign a name  Recording: Information must be recorded  Over 300,000 different kinds of plants have been cataloged!

4. Identification  Learn to recognize major groups of plants by learning key features of families is a major step to identification.  Learn the anatomy and key descriptions of plants to correctly identify them. (Use plant dichotomous Key)

5. Classification  Uses 7 taxa developed by Carolus Linnaeus  Kingdom  Phylum  Class  Order  Family  Genus  Species

6. Vascular Plants  Vascular Plants include:  Ferns and allies  Gymnosperms: Cone Bearing  Angiosperms: Flowering **Largest group is the angiosperms 235,000 species**

7. What Botanist Look At?  Botanist look at the following parts to classify plants:  Flowers  Stems  Roots  Leaves Flowers Stems Leaves Roots

8. Roots & Function  Functions of roots:  Anchoring  Storage of food and water  Support  Absorb water and nutrients

9. Types of Roots  3 Major type of Roots  Taproot: Carrot  Fibrous Root:  Adventitious Roots: Mangroves

10. Stems & Function  Functions of stems:  Transportation  Support  Storage  Protection

11. Stem Terms  Nodes: Places where leaves are attached  Modified Stems  Tuber: potato  Bulbs: Onion  Corm: Gladiolus  Rhizome: Ginger

12. Leaves & Functions  Functions of Leaves (photosynthesis)  Coniferous Trees: Loose their leaves all the time, but seem to have leaves all year long  Deciduous Trees: Loose leaves all at once
