Leaves contain chloroplasts; which make sugars using sunlight. This is called photosynthesis. One of the by-products of this process is Oxygen. This oxygen sits in the Parenchyma, which is in the middle of the leaf. This gives the leaf a lower density than water; so it floats on the surface. This oxygen, if it is not used by the plant, is later released from the Stoma, which are little holes on the bottom of the leaf; and the leaf sinks.
