Experimental Process and Setup
How many different treatments did we use?
What is 4
Which treatment had the highest number of roots?
What is high auxin
What is auxin?
What is a growth hormone naturally produced by plants
What was our testable question?
What is how does auxin effect root development?
Did a the high concentration of auxin yield the most roots overall?
What is yes
What were the different treatments used?
What is no auxin, low auxin, medium auxin, and high auxin
When did we first see roots in the stem cuttings?
What is the third and final week
What is auxin a primary activator in?
What is adventitious root formation
What was our hypothesis
What is if more auxin is added to the stem cutting of the Peperomia plant, then there will be a more rapid rate of root/stem growth in that plant
What else was observed about the roots besides the number of roots grown?
What is the root type, thin, fibrous, thick, stubby
How many plants were in each treatment?
What is 6
What kind of roots did the control group end up producing?
What is thin and fibrous
According to previous studies, what is the most beneficial auxin concentration for plants?
What is medium
What is one question we asked about our own experiment after gathering results?
What is what would have happened if we had a longer period of time to conduct the experiment?
Did auxin increase the rate of root production?
What is no
What type of plant was used?
What is Peperomia
Are our results statistically significant and why?
What is no because the error bars in the graph overlap
How is auxin used with stem cuttings?
What is the stem cutting is dipped in auxin
What is a future testable question that we considered based off of our results?
What is how does the same concentration of auxin effect different types of plants?
What was the approximate mean for the control group?
What is one error that may have effected the results?
What is the size of the leaf on the Peperomia cutting
What was the approximate standard error?
What is .6
What does auxin regulate?
What is cell expansion, rates of cell division, maintenance of pattern during growth and development
What is one way that this knowledge is applicable?
What is (Multiple Answers Possible)
What was the approximate average mean for the high auxin group?
What is 4.
