To clarify: We boiled alcohol with a leaf and tested for starch with iodine (present in the veins), We also covered a leaf with tin foil and came back the next day.

This lab was suppose to show us glucose is made by the leaf, but all it proves is that starch is in the veins, right?

How are starch and glycogen similar and how do they differ?
Startch have two types of polymer chain,one is amylose and another is amylopectin.Amylose is simple straight chain of glucose(1--->4 linkage),while amylopectin have branching.At branching point,there is 1--->6 linage and 1--->4 linkage in every subchain. So,in startch 1-6 linkage comes after 20 to 25 gucose monomer,while in gycogen this linkage comes very frequently.....
