When you have direct control over something it becomes an independent variable.
e.g. you are adding different concentrations of extracts. this is an independent variable.
The germination of seeds is affected by the different concentrations of extracts, therefore the germination or change in germination profile is dependent variable.
Another independent variable is the plant parts e.g. leaves, stem, peel, etc. this is a non numerical variable.
Hope that clears the confusion
