  1. Name some roots
    • Cassava
    • Glycyrrhiza
    • Carrots
    • Radishs
    • Beets
    • Onions
  2. Root that has 20X the sugar
    licorice
    good and plenty
    Glycyrrihiza
  3. Root that is 3rd in worlds diets
    grows in poor soil
    we use as tapioca pudding
    cassava
  4. First organ from seed:
    • radicle
    • primary root
  5. * dicot common
    * 1st main root
    * reaches deeper H2O
    Tap Root System
  6. * monocot common
    * shallow
    * dryer places for rain
    Fiberous Root System
  7. * forms at part of plant that comes out at a place not expected
    * like stems & petiole
    Adventitious System
  8. 3 regions of young stem
    • 1. Root Cap
    • 2. Branch Roots
    • 3. Border Cells
  9. * collection of apical meristem cells
    * protection
    * mucigel, lubercation
    * senses gravity by root cap cells
    Root Cap
  10. *developes from inside of young stem
    Branch roots
  11. What the young stem flakes off
    Border Cells
  12. Root Cap description
    • Bottom:
    • * Root Cap
    • * Apical meristem
    • outside->in
    • * protoderm
    • * ground meristem
    • * procambium
  13. Root Tip regions and what developes there
    • 1. Cell Division-cells
    • 2. Elongation-phloem
    • 3. Maturation= xylem/root hairs
  14. What are root hairs used for?
    H2O absorption
  15. * controls flow and passage
    * symplastic- through cell membranes via plasmodasmada
    * apoplastic- btwn cellular spaces
    * casparian Strip-H2O proof
    Endodermis
  16. * between cellualr spaces to endodermis membrane, must be accepted
    Apoplastic
  17. Through cells membranes plasmodasmada bridges
    symplastic
  18. * only in roots
    * 1st main function is lateral roots generation
    * 2nd main function is vascular cambium
    * 3rd main function is cork cambium creation
    Pericycle
  19. * divides cells btwn sylem & phloem
    * pericycle divides in other spaces
    * continous growth
    * pushes phloem out
    * cortex & epidermis lost
    The vascular cambium being made by the pericycle in woody young stems
  20. * division of pericycle lateral roots @ protosylem poles
    pushes cells out
    Lateral roots generation of pericycle function in young roots
  21. * biannual life cycle
    * propagative
    * aerial roots
    * Roots above ground
    * Pneumatophores
    Specialized Roots
  22. *forms adventitious buds
    * buds develop into suckers
    Propagative
  23. epiphytes
    -above ground
    -can carry out photosynthesis
    -can form roots is leaves
    Aerial Roots
  24. *support structure
    * prop roots ie corn
    * aerial roots - baryan
    * buttress roots
    Roots above ground
  25. * breathing roots
    * black mangrove
    * air sacks conduct air breathing
    Pnuematophores
  26. Initmate long term relationship btwn organisms
    -parasitism
    -mutualism
    -commonsalism
    Symbiosis
  27. Example of parasitism:
    Haustorium
  28. * mycorrhizae
    * fungus feeds roots
    * transfers photosynthetic nutrients
    Mutualism
