Angiosperm notes

  1. 1. ANGIOSPERMS
  2. 2. Morphology vs. Anatomy <ul><li>Morphology is the study of the external structure of plants </li></ul><ul><ul><li>Ex. placement of leaves along a stem </li></ul></ul>
  3. 3. <ul><li>Anatomy is the study of the internal structures of plants </li></ul><ul><ul><li>Ex. the arrangement of cells and tissue within a leaf </li></ul></ul>
  4. 4. MONOCOTS VS. DICOTS <ul><li>Angiosperms are split into 2 classes </li></ul><ul><li>Monocots – single cotyledon (seed leaf) </li></ul><ul><li>Dicots – two cotyledons </li></ul><ul><li>Cotyledon - seed leaf, one in moncots and two in dicots; </li></ul><ul><li>primary embryonic leaf within the seed in which nutrients for the new plant are stored (left- dicot, bean; right- monocot, corn) </li></ul>
  5. 5. Roots, Stems & Leaves <ul><li>Roots </li></ul><ul><ul><li>anchor the plant into the soil </li></ul></ul><ul><ul><li>Absorb minerals and water </li></ul></ul><ul><ul><li>Conduct water and nutrients </li></ul></ul><ul><ul><li>Store food </li></ul></ul>
  6. 6. Monocot root Cross section
  7. 7. Dicot Root cross section
  8. 8. <ul><li>Stems </li></ul><ul><ul><li>May be vegetative (leaves) </li></ul></ul>
  9. 9. <ul><ul><li>Stems may be floral (flowers) </li></ul></ul>
  10. 10. <ul><ul><li>Stems </li></ul></ul><ul><ul><li>Have alternation of nodes (points at which leaves are attached) </li></ul></ul><ul><ul><li>Have internodes (stem segments b/w nodes) </li></ul></ul>
  11. 11. Modified Stems <ul><li>Stolons are horizontal stems that grow along surface ex. strawberry runners </li></ul>
  12. 12. <ul><li>Rhizomes are horizontal stems that grow underground ex. Irises </li></ul>
  13. 13. <ul><li>Tubers are enlarged ends of rhizomes that store food ex. potatoes </li></ul>
  14. 14. <ul><li>Bulbs are vertical, underground shoots with fleshy leaf bases modified food storage </li></ul>
  15. 15. Monocot stem cross section
  16. 16. Dicot stem cross section
  17. 17. <ul><li>Leaves </li></ul><ul><ul><li>Main photosynthetic organs of plants </li></ul></ul><ul><ul><li>Consist of a blade and a stalk (petiole) which joins the leaf to the stem </li></ul></ul><ul><ul><li>Grasses and many monocots lack petioles </li></ul></ul>
  18. 18. <ul><li>Some monocots have petioles </li></ul>
  19. 19. Venation <ul><li>Monocots have parallel major veins that run the length of the leaf blade </li></ul><ul><li>Dicots generally have a multibranched network of major veins </li></ul><ul><li>All leaves have numerous minor cross veins </li></ul>
  20. 22. Modified Leaves Spines, thorns and prickles Tendrils
  21. 24. SUMMARY
  22. 27. WHAT DO I NEED TO KNOW <ul><li>Unifying characteristics of gymnosperms </li></ul><ul><li>Unifying characteristics of angiosperms </li></ul><ul><li>Explain how gymnosperms are adapted for survival in a land environment with respect to the following </li></ul><ul><ul><li>Alternation of generation </li></ul></ul><ul><ul><li>Roots </li></ul></ul><ul><ul><li>Stems </li></ul></ul><ul><ul><li>Leaves </li></ul></ul><ul><ul><li>seeds </li></ul></ul><ul><ul><li>Pollen </li></ul></ul><ul><ul><li>Vascular tissue </li></ul></ul>
  23. 28. <ul><li>Use specimens to differentiate between monocots and dicots </li></ul><ul><li>Describe how angiosperms are adapted for survival in a land environment with respect to the following </li></ul><ul><ul><li>Alternation fo generations </li></ul></ul><ul><ul><li>Flowers </li></ul></ul><ul><ul><li>Pollen </li></ul></ul><ul><ul><li>Enclosed seeds </li></ul></ul><ul><ul><li>Fruit </li></ul></ul><ul><ul><li>Roots </li></ul></ul><ul><ul><li>Stems </li></ul></ul><ul><ul><li>Leaves </li></ul></ul><ul><ul><li>Vascular tissue </li></ul></ul>
  24. 29. <ul><li>Compare the ways in which mosses, ferns, gymnosperms and angiosperms have adapted to a land environment </li></ul><ul><li>TEXT </li></ul><ul><ul><li>Read all the following… </li></ul></ul><ul><ul><li>Ch 22 all sections </li></ul></ul><ul><ul><li>Ch 23 most pictures, 23-4(modified roots),23-5,23-7 </li></ul></ul><ul><ul><li>Ch 25-1,25-2 </li></ul></ul><ul><ul><li>Answer the following questions… </li></ul></ul><ul><ul><li>Page 484&485 all </li></ul></ul><ul><ul><li>Page 514&515 (mc#2,TF#1,2,4,5,6,8 WR#1,4 CM#3,4,6 CCT#2,3,4,5,7,8) </li></ul></ul><ul><ul><li>Page 548&549 (mc#1-4,7,8 TF#1,3-7 WR#1,3 CM#2,3,4,5,6,8 CCT#1,2,4,6,7 </li></ul></ul>
