2. OBJECTIVES:
- engage participants to activities that would develop their background about Botany, especially Plant Taxonomy;
- appreciate plants economic importance; and
- develop camaraderie among the participants.
3. 4. PLANT TAXONOMY
- science that finds, describes, classifies, identifies and name plants
- Two goals are identification and classification of plants
Plant identificationis the determination of the identity of an unknown plant.Plant classificationis the placing of known plants into groups 5.
- Classifying organisms
- Linnaean taxonomic systemby
- Carolus Linnaeus

MAJOR TAXONOMIC LEVELS plantae magnoliophyta magnoliopsida rosales rosaceae rosa 6. CHARACTERISTICS OF PLANTS
- multicellular
- eukaryotic
- autotrophic
- alternative generations in life cycle
- Undergo photosynthesis
- have a cell wall made of cellulose
7.
- Non-vascular plants
- without avascular system
- possess tissues specialized for internal transport ofwater
Division Bryophyta
- include liverworts and mosses
- lack water-conducting tissues
- have rhizoids, stemlike and leaflike structures
- colonize bare rock
- Liverworts
- flattened, lobed bodies and represent a small fraction of bryophyte species
- With numerous rhizoids
8.
- Examples of Liverworts
9. 10. 11.
- 2. Moss
- stem like structure with radially arrange leaf like structure
Examples of Moss 12. 13.
- Vascular plants
- have vascular tissue
Division Psilophyta
- seedeless vascular plant
- has branched stem and lacks true roots and leaves
- stem is green and carries photosynthesis
- Example of this is whisk fern
14. EXAMPLE OF WHISK FERN 15.
- Division Sphenophyta: horsetail
- Division Lycophyta: club mosses
- seedless vascular plants
- do not produce seed
Examples 16. Division Pterophyta: ferns
- have roots and leaves or stem
- vary in appearance
- low- lying but some are tall
Examples 17. Division cycadophyta: cycads
- extremely ancient group
- sister group to all other living seed plants
- stout and woodytrunk with acrown of large, hard and stiff,evergreen leaves
- havepinnate leaves.
Examples 18. Division Coniferophyta: conifers
- trees or shrubs that bear their seeds in cones
- Some conifers are the oldest plants on earth.
- have either needles or scale-like leaves.
- Most abundant gymnosperms today.
Examples 19. Division Gnetophyta: woody plants
- have different vessel elements
- mostlywoody climbersin tropical forests
