1. PLANTS WITHOUT SEEDS NON VASCULAR

2. 2 TYPES OF PLANTS  NONVASCULAR:  plants that DO NOT have tubes that carry water and food throughout the plant  VASCULAR PLANT:  plants that DO have tubes to carry food and water throughout the plant

3. NEEDED FOR PLANTS TO MOVE TO LAND  Need to support the leaves and rest of the body so that they do not collapse  What would help support the plant?  Stems

4. NEEDED FOR PLANTS TO MOVE TO LAND  Need to obtain water and food.  What helped the plant to get food and water?  Roots, Leaves

5. NEEDED FOR PLANTS TO MOVE TO LAND  Need to transport water and food to all different parts of the body.  What helped the plant to get food and water to all parts of the body?  Vascular tissue( xylem, phloem)

6. NEEDED FOR PLANTS TO MOVE TO LAND  Need to prevent excess water loss to the environment.  What helped the plant to lose less water?  Cuticle: waxy covering

7. 1 st PLANTS TO HIT LAND  MOSSES  LIVERWORTS  HORNWORTS

8. MOSSES, LIVERWORTS & HORNWORTS  Adapted to land by:  Living in places with a lot of water  Remaining small in size  They are Nonvascular  Uses for humans:  Decoration (in gardens)  Soil conditioner  Fuel (dried peat moss)

9. Importance of Non Vascular Plants  Usually the first plants to inhabit a new environment.  Form a thin layer of soil when they die.  They help hold the soil in place which prevents erosion.  Nesting material for birds.  Peat moss can be burned as fuel.

10. MOSSES

11. LIVERWORTS

12. HORNWORTS

13. PLANTS WITHOUT SEEDS VASCULAR

14. SEEDLESS VASCULAR PLANTS  Vascular plants, such as ferns are much better adapted to life on land than nonvascular plants.  Vascular tissue allows materials to be transported quickly and effectively throughout the body of a plant.

15. Characteristics of Vascular Plants  They can grow much taller than mosses and hornworts  They have true leaves, stems and roots  Have a waxy coating on their leaves to prevent water loss  Reproduce by spores

16. Two types of vascular tissue  XYLEM: carries water and minerals throughout the plant  Only goes in 1 direction….UP XYLEM

17. Two types of vascular tissue  PHLOEM: carries food throughout the plant  Goes in both directions PHLOEM

18. Types of seedless vascular plants  Whisk Ferns: can be found in swamplands and dry rocky cliffs  Rhizomes: horizontal stem of a plant that is usually found underground

19. Types of seedless vascular plants  Club Mosses: small, creeping, terrestrial plants

20. Types of seedless vascular plants  Horsetails: they are erect, jointed, brittle and grooved, hollow except at the joints

21. Types of seedless vascular plants  Ferns: have true leaves but lack flowers and seeds  Fronds: part of fern leaf that has the spores  Fiddleheads

22. Parts of Ferns  Fronds: part of fern leaf that has the spores

23. Parts of Ferns  Fiddleheads: uncurled baby ferns

24. Reproduction in plants without seeds  Alteration of Generation: sporophyte (produces spores) turn into a gametophyte (produces a new plant)  Sexual reproduction that requires water for the sperm to reach the egg

25. Helpful effects of Ferns  Popular houseplants  Products from fern are used to grow other plants  Used in crop to house a bacteria that acts as a fertilizer  Some ferns can be eaten as food
