i dont get this.... i dont know what a control means and when people tell me i dont get it.
my problem statement is: Will the roots grow faster when growing in the direction of gravity vs. growing horizontally?
this is me procedures:
1.For the first “seed sandwich,” moisten the blotting paper.
2.Place several seeds on the moist paper, in a grid pattern, several inches apart. Avoid edges because they are most likely to dry out.
3.Place the blotting paper...
A: if you assume the horizontal plate as a representation of "normal" seed growth, then this is the control. All the vertical experiments should be compared to the control.
