Table 2.1 part of the leaf colour with iodine solution green blue‑black white yellow‑brown Explain the results shown in Table 2.1 for the white part of the leaf. This investigation was repeated with a plant that was kept for 24 hours in an environment where all the carbon dioxide was removed. Complete Table 2.2 to predict the results. Table 2.2 part of the leaf colour with iodine solution green white The boxes on the left show the names of some substances that are made in plants.
