If 6.0 milligrams of nitrogen is added for 2,000 milliliters of water, then the mutant plants will have 5% bigger rosette leaves, 5% taller bolt heights, and 2% more siliques will sprout from the main bolt.
Our variable is Nitrogen. We created a urea solution with 6.0 milligrams of nitrogen in 2,000 milliliters of water to treat our plants once a week. Our Arabidopsis plants are treated with four drops of urea. Each drop is 1 millimeter. The independent variable for this experiment is the absence or presence of a treatment of Urea. The dependent variable is the growth of the plant as a result of this change.
Urea was chosen because it increases cellular reproduction and photosynthesis rates. It is also important for the creation of amino acids and proteins which is important for both DNA and RNA. Urea promotes strong stems and lush rosettes for Arabidopsis Thaliana as well.
