Mallory has four aquatic plants of the same size and species. She submerges each plant in a separate beaker filled with 200 mL of water. She then sets each beaker under a different intensity of light. Mallory observes that, of the four plants, the plant in the beaker under the most intense light gives off the most gas bubbles in a 20 min period.Which of the following statements best explains Mallory's observations?

Question

Quizplus · Accepted Answer

Photosynthesis, the process by which plants convert light energy into chemical energy, occurs at a higher rate under more intense light. The gas bubbles observed are oxygen, a byproduct of photosynthesis, indicating that the plant under the most intense light is photosynthesizing at the highest rate.
