Question
Mini Case Study 3: Need to Get My Roots Done Consider this observation. Observation: During an experiment on plant doning a scientist noticed that the root length of the plant clones varied based on the concentration of a hormone that was added to the growth media. Based on this information, please answer the following questions 1. Generate a measurable hypothesis to explain these observations. 2. Based on your hypothesis generate a prediction about the growth of plant clone roots in response to the hormone. 3. Outline an investigation to test your hypothesis in the space below, identifying the dependent and independent variables. Additionally, make sure you address your controls and replicates!Explanation / Answer
1) The root length of plant clones are dependent on hormone concentration.
2) The more concentration of hormone will make more growth of plant clone roots.
3) Dependent variable: The growth of plant clone roots.
Independent variable: The concentration of hormone.
Plant clones will be grown on media containing hormone or without hormone.
Control 1: experiment media prepared without any hormone added.
Control 2: experiment media prepared without any hormone added.
Plate 1: Hormone (1 IU) added to the media
Plate 2: Hormone (2 IU) added to the media
Plate 3: Hormone (3 IU) added to the media
The growth of plant clone roots will be measured.
