Concept:Analysis involves breaking down information into parts to understand relationships, predict outcomes, or evaluate procedures. This question requires reasoning about the necessity of a step in the experiment.
Explanation:The activity demonstrates the iodine test for starch. The leaf is boiled in spirit to remove chlorophyll before adding iodine.
Option A asks: "Can this test be done without removing chlorophyll?"
To answer, students must analyze the purpose of removing chlorophyll. They must think about whether the green colour hides the blue-black colour change. This requires evaluating cause and effect and predicting an alternative procedure.
The other questions test recall or observation, not analysis.
Option B asks about safety precautions (simple recall).
Option C asks about handling spirit (procedural knowledge).
Option D asks about colour change (direct observation).
Only option A demands higher-order thinking—breaking down the experimental steps and judging the necessity of each step.
Answer:The question that assesses ‘analysis’ is: "Can this test be done without removing chlorophyll?" (Option A).
