a student conducted an experiment on plant growth . Plat A was fed a different fertilizer than Plant b. before the experiment began, plant a measured 14 centimeters tall,and plant b measured 16 centimeters tall. at the end of the experiment plant a measured 18.2 centimeters tall and plant b measured 20 centimeters tall, which plant a or b grew at a greater rate?
Plant A grew at a greater rate.
Plant A grew a total of 18.2-14 = 4.2 cm. Plant B grew a total of 20-16 = 4 cm.
Since they grew over the same time period, Plant A had a greater rate of growth.
