Detailed explanation-1: -The independent variable should be the amount of water, because the height of the plant is not going to affect the amount of water. The dependent variable would be the height of the plant because it is relying on how much water is being added to it.
Detailed explanation-2: -If a plant’s soil has too much water, the roots can rot, and the plant can’t get enough oxygen from the soil. If there is not enough water for a plant, the nutrients it needs cannot travel through the plant. A plant cannot grow if it doesn’t have healthy roots, so the proper balance of water is key when growing plants.
Detailed explanation-3: -Independent variable: amount of sunlight. Dependent variable: growth of plant. Controlled variables: type of plant (genetic makeup), number of seeds, availability of water, time.
