Mike has four aquatic plants of the same size and the same species. He submerges the plants in a separate beaker filled with 200 ml of water. He then sets each beaker under a different intensity of light. Mike 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 minute period.

Which of the following statements best explains Mike's observations?

a

Gases in the leaves of plants expand most under the most intense light

b

Photosynthesis occurs at the highest rate under the most intense light.

c

Water evaporates from plants faster under the most intense light.

d

Cells decompose most quickly under the most intense light.
