Answer 2

## Step 1: This question is about a biological experiment that tests for the presence of starch in plant cells, indicating that photosynthesis has recently occurred. The test involves using an iodine solution.## Step 2: Iodine solution is used in this test because it reacts with starch, causing a visible color change. This color change is a key indicator of the presence of starch.## Step 3: The specific color change that occurs when iodine reacts with starch is from its original brown color to a dark blue or black color.
