Test for startch in green leaves?

Question

When we do the test for starch in green leaves then boil it in a beaker for two minutes, we then put it into alcohol? Why do we immense it into alcohol? I've got an exam tomorrow and that's one of the questions that's going to be on it. Help?

Answer 1

Starch is more soluble in alcohol than water?  Too many details missing on your test to be sure what's going on.
