Juan did an experiment to study the rate of photosynthesis in the water plant Elodea. She placed a piece of
Elodea in a beaker of water and set the beaker 10 centimeters (cm) from a lisht source. Juan counted the
bubbles released from the plant every minute for five minutes (min). She repeated the process two more
times. First, she moved the light to 20 cm from the beaker, and then she moved the light to 30 cm from the
beaker. Juan's setup and data are shown below.
