Experiment Qs Seed Germination

State three environmental factors that are necessary for germination. Water / Oxygen / Warmth (correct temperature) (WOW)

Seed Germination What seeds did you use? Mustard / cress / radish / peas

Seed Germination Describe how you carried out the experiment. 4 dishes/ tubes. A: minus water / B: minus oxygen / C: with every thing / D: minus correct temperature / place A, B and C in incubator at 20 °C / place D in fridge / for 2-3 days

Seed Germination State the results of your experiment. All conditions present – growth no oxygen – no germination low temperature – no germination no moisture – no germination

Seed Germination Describe how you carried out the experiment. 4 dishes/ tubes. A: minus water / B: minus oxygen / C: with every thing / D: minus correct temperature / place A, B and C in incubator at 20 °C / place D in fridge / for 2-3 days

Seed Germination Describe how you carried out the experiment. 4 dishes/ tubes. A: minus water / B: minus oxygen / C: with every thing / D: minus correct temperature / place A, B and C in incubator at 20 °C / place D in fridge / for 2-3 days

Seed Germination Describe the results of this experiment, including the result of the control. All conditions present – growth no oxygen – no germination low temperature – no germination no moisture – no germination

Seed Germination What seeds did you use? Named seed, e.g. cress, mustard, etc.

Seed Germination Explain how you set up a control for the investigation. 4 dishes/ tubes. A: minus water / B: minus oxygen / C: with every thing / D: minus correct temperature / place A, B and C in incubator at 20 °C / place D in fridge / for 2-3 days

Seed Germination How did you deprive some of the seeds of oxygen? Anaerobic jar or other

Seed Germination How did you ensure that some of the seeds were deprived of a suitable temperature for germination? Put in fridge or freezer or cold environment

Seed Germination State the results of the investigation, including those of the control. All conditions present – growth no oxygen – no germination low temperature – no germination no moisture – no germination

Seed Germination For what purpose did you use an anaerobic jar in the course of your practical activities? To see if O 2 is necessary for germination / to limit or reduce O 2

Seed Germination Describe an experiment to demonstrate the factors you essential for germination. Vessel / seeds / experiment or one factor missing / explain how one factor was removed / control or all three factors present / identical conditions / leave for period/ observe or state result
