  1. Plant Diary 2008 Individual Student Project Plant Physiology

  2. Objectives • Watch a plant develop • Identify parts • Measure growth • Explain physiology behind development • Tie what you see with what you know • Prepare for the final • Have major points for a project

  3. The Parts • Seed germination • Seedling growth • Location of growth in root, stem, leaf • Physiology explaining phenomena • Report turned in at end of semester

  4. 1. Germinating Seeds • Grow in petri dishes with lids on bottom • Corn and beans (3 ea.) • Very wet paper towel • Keep warm • Oxygen to seeds • Observe daily • Flat first 2 days • Tilted next 3 days

  5. What to Observe • Color, texture • Changes in shape & size • Organ formation & growth • Anything else you see • Write this down • Some on paper • Some on image

  6. The Image • You could draw or take pictures (hard) • Instead • Observe your seed (choose one) • Match yours with the images provided • Write down the number of the image • Download the image from the class website • Use this image for your report

  7. What to do with the Image • Label the parts right on the image • Internet or texts to get part names • Measure what you can • Weight • Height, Width (of parts and whole) • Area of flat things like leaves • Add your notes next to the image • Examples in manual, help in lab

  8. 2. Seedling Growth • Seedling will be shown live on website • Save images you want right from web • Probably twice daily right at emergence • Less than daily near end • Use development to decided how often • Treat images as for seed germination • Seedlings will grow for 2 weeks • Help given in lab

  9. 3. Location of Growth • Marks on tissue (see manual) • Get images on 2 adjacent days • Compare 2 images • Germinating seeds for root growth • Seedlings for stem and leaf growth

  10. The Physiology • Explain how what you see happened • Don’t go into biochemical details • Do cover • Water

  11. The Report • Use PowerPoint (easiest) • Print in color (“Handouts”) • Four “slides” per page • NO plastic cover

  12. Report Organization • Tell the story of your plants • Bean & corn stories separate OR • By time (day 1, both plants)

  13. Each “Slide” Title Here Labeled photo or graph here Description and interpretation of what’s going on here (bullets or not)

  14. Today Start Seeds • Teams of 4 people & choose a name • Cut out paper towel • Draw circle around smaller petri dish part • Cut 4 layers of towel (layer=thinnest) • 2 on bottom, 2 on top (top is shortened) • Use larger part (lid) on bottom • Weigh 3 seeds & place in dish • Keep weights separate (L, M, R) • Look at your seeds and describe • Take the image provided for time 0

  15. To the Lab • Lab will be open all week (Room 75) • Go daily and observe (take notes) • Weigh seeds (can cooperate) for 2-3 days • Choose an equivalent image and seed & write down the image number • Everything else will be explained in lab
