Plant Lab
Materials
  • 2 petri dishes
  • paper towel
  • 4 corn seeds
  • 4 pea seeds
  • Soil
  • Cups
  • gibberellin and auxin
Purpose

The purpose of this lab is to observe the development of plant seeds.

Predictions

The plants with gibberellins applied will initially grow faster than the control, whereas the auxin plants will grow later in the experiment

Procedure

  • Moisten the paper towel
  • Lay paper towel in bottom of petri dish
  • Place 4 corn/pea seeds on paper towel
  • Cover seeds with remaining paper towel
  • Close the petri dish
  • Once a day, remove te seeds and place them in a new, moistened paper towel.
  • When the seeds both have a root shoot, place them them in a cup filled with soil, with the root down and if there is a shoot, place it above the soil.
  • Spread the different hormones on different plants' stems, leaving one plant as control.
Data/Observations

Peas
5/6Began. Planted seeds
5/10All four seeds are dead. Replanted all four.
5/11all grew
5/17planted seeds 3 and 4, one died.
5/19 plant 1 is 10 mm, plant two is 15, plant 3 is 35
5/21plant one is 10mm, plant two is 25, plant three is 35

Corn
5/6began
5/10plant 1 is 9mm, plant 2 is 13mm, plant 3 is 13mm and plant 4 is 16mm. All plants began the germination process (took up water, expanded and burst, grew a root)
5/11plant 1 is 10.5 mm, 2 is 13mm 3 is 13mm and 4 is 18mm
5/17planted all four
5/19plant 1 is 18mm, 2 is 20mm, 3 is 20mm, 4 is 30mm
