Why must controls (such as plants given water only) be used in the fertilizer experiment
Controls are necessary in the fertilizer experiment to provide a baseline for comparison. By having plants that receive only water, researchers can isolate the effect of the fertilizer being tested. This helps ensure that any observed changes in plant growth or health can be confidently attributed to the fertilizer treatment.

The control variable in this experiment would be the plants that do not receive any fertilizer. By comparing the growth of plants with fertilizer to those without, researchers can determine the effect of adding fertilizer on plant growth.

fertilizer
A good scientific experiment is when you have one or two things and you keep one the same and make the other have a difference: example: You have two plants. you want to know which fertilizer makes them grow taller. So you buy Super fertilizer and Dan's Fertilizer. you put both fertilizers on the different plants so plant one has Super fertilizer and plant two has Dan's fertilizer. you keep the amount of water, sunlight, soil and ECT the same.
Yes, you can add fertilizer to water when propagating plants to provide nutrients for healthy growth.
