Plants2 plant parts seeds: germination, cotyledons, tropisms, includes labs, visuals, & video clips

  1. 1. Plants 2a: Plant Parts PPt. by, Robin D. Seamon SEEDS
  2. 3. <ul><li>SEEDS: </li></ul><ul><li>Activities </li></ul><ul><li>Seed tasting LAB: mango, pomegranite, coconut, avocado, kiwi </li></ul><ul><li>Seed Hunt LAB: </li></ul><ul><li>Seed Dissection LAB: </li></ul><ul><li>Seed Planting: </li></ul><ul><li>Seed Experiments: </li></ul>
  3. 4. <ul><li>Seeds : seeds are made by the plant so that the plant can reproduce itself (make more.) </li></ul><ul><li>Have lots of stored energy in them for the young plant to start life. That’s why animals eat them. </li></ul><ul><li>Germination : the process of a seed sprouting into a young plant. </li></ul><ul><li>To germinate, some need digestion, some need cold, some need warmth, some need fire, all need water. </li></ul>
  4. 5. <ul><li>Roots grow down geotropism (following gravity) </li></ul><ul><li>Stem grows up phototropism (following light) </li></ul><ul><li>They travel by wind, sticking to animal fur, in water, and by being eaten by animals/people </li></ul><ul><li>We eat some seeds </li></ul><ul><li>There are two types of seeds: Monocots , Dicots </li></ul>VIDEO: HSW seed dispersal
  5. 6. <ul><li>COTYLEDONS: </li></ul><ul><li>Monocots have one cotyledon, (corn, rice, wheat, grasses) </li></ul><ul><li>Dicots have 2 cotyledons (bean plant, roses, cacti) </li></ul>
  6. 7. Seed Parts <ul><li>Seed coat </li></ul><ul><li>Cotyledons (food) </li></ul><ul><li>Small plant embryo </li></ul>
  7. 8. Label the type of seed & its 3 parts. <ul><li>Seed coat </li></ul><ul><li>Cotyledons (food) </li></ul><ul><li>Small plant embryo </li></ul><ul><li>Gymnosperm seed </li></ul><ul><li>Dicot seed </li></ul><ul><li>Monocot seed </li></ul>
  8. 9. <ul><li>SEED GERMINATION STEPS: </li></ul><ul><li>Water soaks into the seed coat </li></ul><ul><li>Seed coat splits </li></ul><ul><li>Root grows down </li></ul><ul><li>Small embryo grows up, taking cotyledons with them </li></ul><ul><li>Cotyledons turn GREEN with sunlight (photosynthesis) </li></ul>VIDEO: Germination of a Seed 1.5 min
  9. 10. <ul><li>PLANT LABS: </li></ul><ul><li>Leaves: Identify & graph your collection into journal; view & draw fern spores; Answer questions in Plant Journal. </li></ul><ul><li>Flowers: identify & draw 5 local spring flowers on white paper. Glue into journal. Roots: identify fibrous & taproots; draw 7 label root parts in journal; Answer questions in Plant Journal. </li></ul><ul><li>Seeds: seed dissection: label 3 parts of the seed into journal; observe pine nuts in pinecones-- sketch into journal; Answer questions in Plant Journal. </li></ul><ul><li>Stems: Compare three different types of bark. Notice the color & texture. How do the grains run? Is there a pattern? Create a bark rubbing with a dark crayon (rubbed sideways). Sketch the three specimens. </li></ul>Header:
  10. 11. <ul><li>LAB: SEEDS </li></ul><ul><li>RULES: BE CAREFUL DISSECTING THE SEEDS. </li></ul><ul><li>What is the purpose of a seed? ______________________________________ </li></ul><ul><li>What is the process of a seed sprouting into a young plant? ________________ </li></ul><ul><li>How do seeds travel? _____________________________________________ </li></ul><ul><li>What is the difference between a monocot & a dicot? _____________________ ______________________________________________________________________________________________________________ </li></ul><ul><li>Sketch the following parts of your dissected lima bean seeds: (seed coat, cotyledon, small embryo) </li></ul><ul><li>Name 5 seeds that we eat. __________________ ________________________________________ ________________________________________ </li></ul>Header:
