Answer
1: opens up; 2: water
Explanation
When light intensity increases, this changes the environmental conditions around a plant. Plants respond to this change by opening their stomata for process of photosynthesis. The opening of these tiny holes on the leaf surface allows the plug for more gas exchange during photosynthesis. Therefore, carbon dioxide is able to enter the plants more freely. That phrase is expressed by option (1) with "opens up". Then, as the stomata are open, the process of transpiration can accelerate by water escaping from the interior of the plant to the outside. This phenomenon can be seen in option (2) "water". So, according to the role of light intensity, stomata and the rate of transpiration, the complete answer would be "1: opens up; 2: water", as it correctly completes the given statement. To note option, "1: closes; 2: glucose", "1: closes; 2: water", "1: opens up; 2:glucose" are incorrect because when the light intensity is higher, the sustenance doesn't close, and glucose doesn't escape from stomata during transpiration, it's, in fact infra-plant chemical compound.
