Answer 2

Ok, not sure where you get the book, but I'll assume you have a lab. You will need three leaves, fresh ones(of the same plant species, and preferably in similar condition and the same size), and three containment cells, in the first you have your control, a leaf and plain old air, in the second, you have an atmosphere saturated with oxygen, and in the third an atmosphere saturated with carbon dioxide, you should only need around thirty minutes to see tangible results- that being a change of the level of oxygen, if the hypothesis is correct the level of oxygen in the chamber with plain air should rise a little, the environment with the higher oxygen should rise by less, and the carbon dioxide should rise by more, hope that helps.
