Question

What if we put iodine on fallen leaves will it change colour

Answer 1

Answer:

yes

Explanation:

Leaf colour comes from pigments. These are natural substances produced by leaf cells to help them obtain food. The three pigments that colour leaves are chlorophyll (green), carotenes (yellow) and anthocyanins (reds and pinks).

As summer turns into autumn, the shorter days and cooler nights trigger three major changes in the leaf which have consequences for its colour.

Answer 2

Answer:

Explanation:The green leaves contain chlorophyll and, in the presence of sunlight, carry out photosynthesis, thus forming starch. When dipped in iodine solution, the iodine on these green leaves willturn blue-black because of how iodinereacts with amylose in the plant.
