A student is setting up an experiment. The student has twenty identical young plants and will try to answer this question: How does the amount of water given to these plants each day affect how tall the plant will grow? State an appropriate hypothesis for this experiment.

if to much water the roots die if to less cant get oxygen

Explanation:

so much water is in the soil of the plant, roots will die, and the plant cannot get enough soil oxygen. If a plant does not have enough water, it can't move through the plant with the requisite nutrients. If a plant does not have good roots, it cannot grow, and so the correct water balance is important for growing plants.
