  1. Kingdom PlantaeLand Plants Mr. Skirbst Life Science Topic 14

  2. Land Plants

  3. Requirements Land plants need to …

  4. Requirements Land plants need to … • Provide support (so they don’t collapse)

  5. Requirements Land plants need to … • Provide support • Obtain water + minerals

  6. Requirements Land plants need to … • Provide support • Obtain water + minerals • Transport materials (food, water + minerals)

  7. Requirements Land plants need to … • Provide support • Obtain water + minerals • Transport materials • Prevent water loss

  8. Requirements Land plants need to … • Provide support • Obtain water + minerals • Transport materials • Prevent water loss • Get sperm & egg together!

  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 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 Outer bark (hard & protective) Typical structure: 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 Needle-shaped (ex. Pine, spruce, hemlock, larch)

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

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

  43. Vascular Tissue Dissection
