Plant Diary 2008 Individual Student Project Plant Physiology 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 The Parts • • • • • Seed germination Seedling growth Location of growth in root, stem, leaf Physiology explaining phenomena Report turned in at end of semester 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 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 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 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 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 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 The Physiology • Explain how what you see happened • Don’t go into biochemical details • Do cover – Water The Report • • • • Use PowerPoint (easiest) Print in color (“Handouts”) Four “slides” per page NO plastic cover Report Organization • Tell the story of your plants • Bean & corn stories separate OR • By time (day 1, both plants) Each “Slide” Title Here Labeled photo or graph here Description and interpretation of what’s going on here (bullets or not) 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 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
