TITLE:- Presence of starch in leaves
AIM:- To Show Presence of starch in leaves.
MATERIAL REQUIRED:- 1. Beaker 2. Test tube , 3. Bunsen burner. 4. water bath 5. Ethanol 6. Tripod stand
7. leaf
PROCEDURE:- let us consider Beaker , Test tube , Bunsen burner, water bath , Ethanol ,Tripod stand and leaf as shown in figure .
Let us take a leaf from a plant with soft and thin leaves and well exposed to sun light.
* boil the leaf in methylated spirit removal of chlorophyll.
*take the leave carefully from test tube by using a brush.
*spread the leaf in Petridish add few drops of betadine solution on it. Again observe leaf.
