By removing different numbers of leaves from plants in each test group and measuring their growth under the same conditions, we can observe the effect of leaf removal on plant growth. If the plants with fewer leaves show stunted growth or die, it would indicate that leaves are necessary for plant growth. Exposing plants to different amounts of sunlight or painting leaves with clear nail polish would not provide a direct measure of the necessity of leaves for plant growth.
