Plant Growth and Development

1
Plant Growth and Development

• A study of Seeds

2
Three subsections

• Seed anatomy
• Germination effects of extreme heat
• Germination seed treatments

3
Seed anatomy

• Dissect and diagram a bean, pea and corn seed
  label parts
• Test with iodine (for what?)
• Test corn with Benedicts solution (for what?)

4
Germination effects of boiling

• 50 beans divided into two groups of 25
• Boil one set of 25 for 10 minutes
• Plant both sets of 25 beans indicate which is
  control and which is variable
• Determine germination of each group
• Why?

5
Germination seed treatments

• Three sets of 10 okra seeds
• One set soaked in H2SO4
• One set notched
• One set unaltered
• Plant each set of seeds in petri dish with
  moistened filtered paper, covered with foil
• Check germination daily
• Why?

Lab Report

• Introduction purpose of experiment and
  hypothesis
• Materials and Methods list materials, write
  method in paragraph form in past tense (tell what
  you did)
• Results drawings, table and graphs
• Discussion what was learned accept or reject
  hypothesis research reasons for findings
