conditions needed for germination practical

Cards (8)

  • what is the set up for this practical
    4 petri dishes with cotton wool base
    same number off seeds in each dish
    have 4 conditions
    leave till growth is seen
    record what percent of seeds have germinated
  • what are the 4 conditions
    light (warmth) + water
    dark + water
    light (warmth)
    dark
  • what is the independent variable (what are we changing)
    light or no light and water or no water
  • what is the dependent variable (result from independent variable)
    whether the plant germinates or not
  • what is the control variable (what stays the same)
    number of seeds, amount of water, number of days
  • what is the conclusion
    plants can still grow with no light because the still do as seeds in soil because those seeds still have shoots and roots and grow
  • what is the result
    90% of the seeds that were in light and water germinated, 90% of seeds that were in dark and water germinated, none of the seeds that were in light and no water germinated and none of the seed that were in the dark and no water germinated
  • germination
    the process of seed starting to grow
