Explanation / Answer

1) No the sugar molecule won't pass the tied and unbroken bag because the sugar molecule is too big to pass through the bag as the membrane is made up of nearly stacked fatty acids. These fatty acid molecules only allow to pass through hydrophobic molecules and small uncharged molecules. As, sugar is too big, it won't be able to pass through this membrane.
