Testing a Leaf for the Presence of Starch
Testing a leaf for starch is the simplest photosynthesis lab.The test for starch in a leaf is also a part of the other photosynthesis experiments.
The video above shows the steps in Testing a Leaf for the Presence of Starch. The Procedure outlined below is slightly different.
In the light - independent stage enzymes catalyse the reduction of carbon dioxide by hydrogen. The carbohydrate, glucose is first formed. Glucose may be immediately used, translocated in the form of fructose or sucrose or stored as starch granules.
The overall equation for photosynthesis is:
