Which of the following is most likely to be TRUE? [9c-25]
1. Plants that naturally grow in the shade often have larger leaves to increase the surface area for photosynthesis.
2. There is less carbon dioxide around plants at night because it has been used up in photosynthesis during the daylight hours.
