A star-shaped figure was cut in the black paper strip used for covering the leaf of a destarched plant used for demonstrating that light is necessary for photosynthesis. At the end of the experiment, when the leaf was tested for starch with iodine, the star-shaped figure in the leaf was found to be: Correct Answer Blue-black

The correct answer is Blue-black.

  • A star-shaped figure was cut in the black paper strip used for covering the leaf of a destarched plant.
    • It was used for demonstrating that light is necessary for photosynthesis.
    • At the end of the experiment when the leaf was tested for starch with iodine, the star-shaped figure on the leaf was found to be blue-black in colour.
    • It was exposed to light and hence, starch was formed in this part of the leaf.

Additional Information

  • Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy.
    • During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

A teacher of Class VII demonstrates the following activity in the class: “A leaf is put in a test tube and spirit is poured over it. Then the test tube is put in a beaker half-filled with water and heated till the leaf is discoloured. The leaf is then taken out and a few drops of iodine are put on it. The leaf turns blue-black in colour.” After this activity, the teacher gives some questions for the assessment of various indicators of learning. Which of the following would assess ‘analysis’?
