1. PLANT CLASSIFICATION

2. Bryophytes - Mosses Bryophytes Are small, low-lying, (generally) moisture-loving plants No xylem or phloem Need water to reproduce Have no roots, stems or leaves, only filamentous rhizoids

3. Bryophytes - Mosses Green part is independent and haploid Brown stalk is dependent and diploid

4. Bryophytes - Liverworts Gametes produced In little umbrella structures Gemma Cups

5. Bryophytes - Hornworts Sporophytes are like little horns

7. Lycophyta – Club Mosses Only a few centimeters high Have vascular tissue Prominence during Carboniferous era Christmas fern

8. Sphenophyta - horsetails Have hollow, jointed stems with whorls of scale-like leaves Silica “Scouring Brush” Also Carboniferous

9. Pterophyta - Ferns Vascular Have phloem to carry food to roots Have xylem to carry water to fronds Produce Spores in Sori

10. Pterophyta - Reproduction

11. Plant Classification – Part 2 The Seed Plants Gymnosperms Angiosperms

12. Gymnosperms Gymnosperm means naked seed Sexual Reproduction Vascular

13. Ginkophyta – Ginko biloba Separate male and female trees Fan-shaped leaves

14. Cycadophyta - Cycads Short, palm-like trees Seeds are produced in cones with male and female cones on separate tree

15. Coniferophyta Cone- bearers Needle- like, scaly leaves

16. Coniferophyta - Reproduction

17. Angiosperms Have Seeds in Fruits Flowers with ovaries that become fruits Vascular Sexual Reproduction Monocots and Dicots

18. Anthophyta Flowering plants Seed enclosed in a fruit Newest plants

19. Anthophyta - Reproduction pollen and ovules
