Getting to Know Plants

Q&A
Question:

Explain an activity to test the presence of starch in a leaf.

Answer:

Take a leaf in a test tube and pour spirit till it completely covers the leaf. Now put the test tube in a beaker having water. Heat the beaker till all the green colour from the leaf comes out into the spirit in the test tube. Take out the leaf and wash it with water. Put it on a plate and pour some iodine solution over it. The iodine solution is brown in colour but when it comes in contact with starch it turns blue-black. The iodine solution will turn blue-black when dropped on the leaf, this confirms the presence of starch in the leaf.

    Check the Size Weight and Color

    While purchasing a cauliflower, look for cream colored heads and also the weight, more than their size. As the heads of the vegetables are tightly compact with each other, so they are heavier than they appear. Look for the heads, which look fresh and also the color of the leaves of the vegetables, whether they are still green or not.
