A student did an experiment with two identical plants, Plant 1 and Plant 2. About 10 mL fertilizer was added to both plants. About 200 mL of water was added to each plant every day. Plant 1 was placed under a desk lamp for 3 hours every day and Plant 2 was placed under the desk lamp for 8 hours every day. The height of the plants was recorded over a period of 5 weeks in the table shown below.
