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

• Taxa

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
