Plant reproduction

  1. 2. <ul><li>Male gamete is pollen </li></ul><ul><li>Female gamete is egg/ovule </li></ul>
  2. 3. <ul><li>Genetic diversity </li></ul><ul><ul><li>Ability to adapt </li></ul></ul>
  3. 4. Male Female
  4. 6. <ul><li>Complete flower = has all major parts (pistil, stamen, sepals, petals) </li></ul><ul><li>Incomplete = missing one or more major part </li></ul><ul><li>Perfect = both male and female parts </li></ul><ul><li>Imperfect = either male or female parts missing </li></ul>
  5. 7. <ul><li>Pollination = transfer of the pollen to the stigma </li></ul><ul><ul><li>Bees, butterflies, bats, wind, gravity, etc. </li></ul></ul>
  6. 8. <ul><li>Cross pollination = two separate plants of same species share pollen </li></ul><ul><li>Self pollination = pollen of same plant lands on its own flowers </li></ul>
  7. 10. Radicle = embryonic root Epicotyl = embryonic plant Hypocotyl = embryonic stem Cotyledon = food storage (protein) Endosperm = food storage (starch)
  8. 11. <ul><li>Fruit serves the purpose of protecting the seeds from drying and also aids in seed dispersal. </li></ul>
  9. 12. <ul><li>End of dormancy </li></ul><ul><ul><li>Absorb water </li></ul></ul><ul><ul><li>Activate enzymes </li></ul></ul><ul><ul><li>Release energy in </li></ul></ul><ul><ul><li>cotyledon/endosperm </li></ul></ul>
