1. Plant
Diversity

2. Plant Divisions/groups
Based on 3 important features
Water-conducting (vascular) tissues
Seeds
Flowers (seeds enclosed in fruit)

3. Ferns and their relatives
Flowering plants
Cone-bearing plants
Ferns and their relatives
Mosses and their relatives
Green algae ancestor
Flowers; Seeds Enclosed in Fruit
Seeds
Water-Conducting (Vascular) Tissue

4. Plant kingdom divided into 4 major groups:
Mosses and their relatives (non-vascular plants)
Ferns and their relatives (seedless vascular plants)
Cone-bearing plants (seed plants-gymnosperms)
Flowering plants (seed plants-angiosperms)

5. Cone-bearing plants 760 species
Flowering plants 235,000 species
Ferns and their relatives 11,000 species
Mosses and their relatives 15,600 species

6. 1. Bryophytes Mosses and their relatives No vascular tissues
Absorb water by osmosis only a few centimeters above the ground  keeps them small
Reproduce using spores (develop into sperm or egg cells)

8. 2. Seedless vascular plants
Include club mosses, horsetails, and ferns.
Have true roots, leaves, and stems
Reproduce using spores

9. Vascular tissue
Made of tube-like elongated cells through which water and minerals are transported.
Include xylem & phloem

10.                                                                                           
Club mosses
Horse tails
Ferns

11. 3. Gymnosperms Bear their seeds directly on the surface of cones
Seed includes embryo, food supply, & protective seed coat
Seed coat
Embryo
Stored food supply
Seed
Wing

12. Examples
Cycads
Gnetophytes
Conifers
Gingko

13. 4. Angiosperms Develop unique reproductive organs known as flowers
Seeds are enclosed in fruit
Most common and familiar plant group

14. Flowering plants divided into 2 groups:
Monocotyledons
Ex. Wheat, grasses, lilies, bamboo, corn
Dicotyledons
Ex. Most trees & shrubs, roses, daisies
Cotyledon = seed leaves

18. Types of Roots
Tap
Fibrous

19. Vascular Tissues/Bundles in Stems
Asparagus
Alfalfa

20. Vascular Tissues/Bundles in Roots
Zea Mays
Ranunculus
