What is the main objective of the experiment described in the paragraph?
To test the presence of starch in a leaf
To understand the effect of light on photosynthesis
To understand the role of CO₂ in photosynthesis
To understand the role of KOH in photosynthesis
Solution
The objective of the experiment described in the paragraph is to understand the role of CO₂ in photosynthesis. This is concluded from the observation that the portion of the leaf exposed to air tested positive for starch while the portion that was in the test tube with KOH, which absorbs CO₂, tested negative.
