9. Kinds of Land Plants 1. Non-vascular (primitive)

10. Kinds of Land Plants Non-vascular (primitive) -Simple structures

11. Kinds of Land Plants Non-vascular (primitive) -Simple structures -Must live in moist areas

12. Kinds of Land Plants Non-vascular (primitive) -Simple structures -Must live in moist areas -Absorb water through all body parts

13. Kinds of Land Plants Non-vascular (primitive) Ex. Mosses, liverworts, hornworts

14. Kinds of Land Plants Non-vascular (primitive) Ex. Mosses, liverworts, hornworts Human uses: used for fuel (burning) & diapers (primitive cultures)

15. Kinds of Land Plants 2. Vascular

16. Kinds of Land Plants 2. Vascular - land plant with vascular tissue

17. Kinds of Land Plants 2. Vascular - land plant with vascular tissue Vascular tissue – a system of tiny tubes

18. 2 Kinds of Vascular Tissue Phloem -

19. 2 Kinds of Vascular Tissue Phloem – transports food - movement is up & down

20. 2 Kinds of Vascular Tissue Xylem -

21. 2 Kinds of Vascular Tissue Xylem – transports water & minerals

22. 2 Kinds of Vascular Tissue Xylem – transports water & minerals -Movement only upwards

23. 2 Kinds of Vascular Tissue Xylem – transports water & minerals -Movement only upwards -Thick cell walls

24. Vascular Plants

25. Vascular Plants have roots, stems, and leaves

26. Roots -Anchor plant in ground

27. Roots -Anchor plant in ground -Absorb water & minerals from soil

28. Roots -Anchor plant in ground -Absorb water & minerals from soil -Store materials (food) for plant for later use

29. Roots 2 Types of roots:

30. Roots 2 Types of roots: 1. Fibrous (tangled mass) (ex. grass)

31. Roots 2 Types of roots: 2. Tap (deep & penetrating) (ex. carrots)

32. Stems - Provide support

33. Stems -Provide support -Transport materials (between roots & leaves)

34. Stems 2 Kinds of stems: 1. Herbaceous (green & soft) (Ex. dandelions)

35. Stems 2 Kinds of stems: 2. Woody (hard & rigid) - made of layers of xylem (ex. trees & shrubs)

36. Stems Typical structure: Outer bark (hard & protective) Phloem Vascular cambium (new growth area) Layers of xylem (growth rings) Pith (soft core)

37. Leaves - Produce food through photosynthesis

38. Leaves Typical Structure:

39. Leaves Photosynthesis:

40. Types of leaves 1. Needle-shaped (ex. Pine, spruce, hemlock, larch)

41. Types of leaves 2.Simple (one main stem; blade in one piece) (ex. Oak, maple, apple, cherry)

42. Types of leaves 3.Compound (leaf blade contains many stems; blade in several pieces) (ex. Locust, hickory, ash, walnut)
